Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537562, here are decompositions:

3 + 31537559 = 31537562
19 + 31537543 = 31537562
223 + 31537339 = 31537562
409 + 31537153 = 31537562
523 + 31537039 = 31537562
571 + 31536991 = 31537562
619 + 31536943 = 31537562
691 + 31536871 = 31537562

Showing the first eight; more decompositions exist.
