Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613242, here are decompositions:

71 + 31613171 = 31613242
251 + 31612991 = 31613242
281 + 31612961 = 31613242
389 + 31612853 = 31613242
503 + 31612739 = 31613242
509 + 31612733 = 31613242
653 + 31612589 = 31613242
659 + 31612583 = 31613242

Showing the first eight; more decompositions exist.
