Chen's theorem is a result in number theory stating that every sufficiently large even number can be written as the sum of either two primes or a prime and a semiprime, a number that is the product of exactly two primes. It is a weakened form of Goldbach's conjecture, which asserts more strongly that every even number is the sum of two primes.

This theorem was proven by Chen Jingrun in 1966 but had to delay publishing his results until 1973 because of political problems in his native China.
