Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612958, here are decompositions:

7 + 31612951 = 31612958
19 + 31612939 = 31612958
67 + 31612891 = 31612958
127 + 31612831 = 31612958
199 + 31612759 = 31612958
211 + 31612747 = 31612958
229 + 31612729 = 31612958
331 + 31612627 = 31612958

Showing the first eight; more decompositions exist.
