Chen Jingrun (May 22, 1933 - March 19, 1996), male, Han nationality, independent person, native of Fuzhou, Fujian, contemporary mathematician.

He studied in the Department of Mathematics of Xiamen University from 1949 to 1953. In September 1953, he was assigned to teach in Beijing No. 4 Middle School. In February 1955, he was recommended by Mr. Wang Yanan, the president of Xiamen University at the time, and returned to his alma mater, Xiamen University, as a teaching assistant in the Department of Mathematics. In October 1957, due to the appreciation of Professor Hua Luogeng, Chen Jingrun was transferred to the Institute of Mathematics, Chinese Academy of Sciences. In 1973, he published a detailed proof of (1+2), which was recognized as a major contribution to the study of Goldbach's conjecture. ? In March 1981, he was elected as a member (academician) of the Chinese Academy of Sciences. He once served as a member of the Mathematics Subject Group of the National Science and Technology Commission and a former researcher of the Institute of Mathematics of the Chinese Academy of Sciences. In 1992, he served as editor-in-chief of Acta Mathematica Sinica.

Describing such a simple problem, even a leading mathematician like Euler could not prove it. This conjecture attracted the attention of many mathematicians. Since Goldbach proposed this conjecture, many mathematicians have been working hard to overcome it, but all have failed. Of course, some people have done some specific verification work, for example: 6 = 3 + 3, 8 = 3 + 5, 10 = 5 + 5 = 3 + 7, 12 = 5 + 7, 14 = 7 + 7 = 3 + 11 ,16 = 5 + 11, 18 = 5 + 13, ...and so on. Someone has checked the even numbers within 33×108 and greater than 6 one by one, and Goldbach's conjecture (a) is true. But rigorous mathematical proof is yet to be made by mathematicians.

Since then, this famous mathematical problem has attracted the attention of thousands of mathematicians around the world. 200 years have passed and no one has proven it. Goldbach's conjecture has thus become an elusive "jewel" in the crown of mathematics. People's enthusiasm for Goldbach's conjecture has lasted more than two hundred years. Many mathematicians in the world have worked hard and tried their best, but they still can't figure it out.
