Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613230, here are decompositions:

3 + 31613227 = 31613230
59 + 31613171 = 31613230
113 + 31613117 = 31613230
239 + 31612991 = 31613230
269 + 31612961 = 31613230
317 + 31612913 = 31613230
491 + 31612739 = 31613230
503 + 31612727 = 31613230

Showing the first eight; more decompositions exist.
