Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613368, here are decompositions:

11 + 31613357 = 31613368
197 + 31613171 = 31613368
251 + 31613117 = 31613368
641 + 31612727 = 31613368
701 + 31612667 = 31613368
821 + 31612547 = 31613368
881 + 31612487 = 31613368
887 + 31612481 = 31613368

Showing the first eight; more decompositions exist.
