Chen's theorem is a result in number theory, specifically in the area of prime numbers. It states that every sufficiently large even integer can be expressed as the sum of a prime and the product of at most two primes. The theorem can be seen as a refinement of the Goldbach conjecture, which posits that every even integer greater than 2 can be expressed as the sum of two primes.
