A theorem on the representation of all sufficiently large odd numbers by a sum of three prime numbers. It is a consequence of the asymptotic formula for the number $I(N)$ of solutions of the equation
$$p_1+p_2+p_3=N$$
in prime numbers, demonstrated by I.M. Vinogradov in 1937:
$$I(N)=\frac{N^2}{2r^3}S(N)+O\left(\frac{N^2}{r^{3.5-\epsilon}}\right),$$
where $N$ is odd, $r=\log N$ and
$$S(N)=\prod_p\left(1+\frac{1}{(p-1)^3}\right)\prod_{p|N}\left(1-\frac{1}{p^2-3p+3}\right)>0.6.$$
Cf. Vinogradov method; Goldbach problem.
