Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612758, here are decompositions:

5 + 31612753 = 31612758
11 + 31612747 = 31612758
19 + 31612739 = 31612758
29 + 31612729 = 31612758
31 + 31612727 = 31612758
97 + 31612661 = 31612758
131 + 31612627 = 31612758
137 + 31612621 = 31612758

Showing the first eight; more decompositions exist.
