In mathematics, Waring's prime number conjecture is a conjecture in number theory, closely related to Vinogradov's theorem. The conjecture is named after the English mathematician Edward Waring and states that every odd integer exceeding 3 is either a prime number or the sum of three prime numbers. The conjecture is known to follow from the generalized Riemann hypothesis.
