Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612628, here are decompositions:

7 + 31612621 = 31612628
31 + 31612597 = 31612628
97 + 31612531 = 31612628
199 + 31612429 = 31612628
277 + 31612351 = 31612628
547 + 31612081 = 31612628
631 + 31611997 = 31612628
787 + 31611841 = 31612628

Showing the first eight; more decompositions exist.
