Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31549516, here are decompositions:

17 + 31549499 = 31549516
113 + 31549403 = 31549516
179 + 31549337 = 31549516
239 + 31549277 = 31549516
563 + 31548953 = 31549516
659 + 31548857 = 31549516
773 + 31548743 = 31549516
839 + 31548677 = 31549516

Showing the first eight; more decompositions exist.
