Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612770, here are decompositions:

11 + 31612759 = 31612770
17 + 31612753 = 31612770
23 + 31612747 = 31612770
31 + 31612739 = 31612770
37 + 31612733 = 31612770
41 + 31612729 = 31612770
43 + 31612727 = 31612770
103 + 31612667 = 31612770

Showing the first eight; more decompositions exist.
