Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612782, here are decompositions:

23 + 31612759 = 31612782
29 + 31612753 = 31612782
43 + 31612739 = 31612782
53 + 31612729 = 31612782
163 + 31612619 = 31612782
193 + 31612589 = 31612782
199 + 31612583 = 31612782
251 + 31612531 = 31612782

Showing the first eight; more decompositions exist.
