Lemoine's problem, named after the French mathematician Georges Lemoine, is a conjecture in number theory concerning the representation of odd integers as sums of prime numbers. Specifically, the conjecture posits that every odd integer greater than 5 can be expressed as the sum of an odd prime and an even semiprime (a product of two primes, where at least one of the primes is 2).
