Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612908, here are decompositions:

17 + 31612891 = 31612908
149 + 31612759 = 31612908
179 + 31612729 = 31612908
181 + 31612727 = 31612908
241 + 31612667 = 31612908
281 + 31612627 = 31612908
311 + 31612597 = 31612908
421 + 31612487 = 31612908

Showing the first eight; more decompositions exist.
