[edit] Personal life
Chen was the third son in a large family. His father was a postal worker. Chen Jingrun graduated from the Mathematics Department of Xiamen University in 1953. His advisor at Chinese Academy of Sciences was Hua Luogeng.
[edit] Research
His work on the twin prime conjecture, Waring's problem, Goldbach's conjecture and Legendre's conjecture led to progress in analytic number theory. In a 1966 paper he proved what is now called Chen's theorem: every sufficiently large even number can be written as the sum of either two primes, or a prime and a semiprime (the product of two primes) — e.g., 100 = 23 + 7·11.
