Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537502, here are decompositions:

163 + 31537339 = 31537502
193 + 31537309 = 31537502
229 + 31537273 = 31537502
349 + 31537153 = 31537502
463 + 31537039 = 31537502
499 + 31537003 = 31537502
631 + 31536871 = 31537502
673 + 31536829 = 31537502

Showing the first eight; more decompositions exist.
