Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537088, here are decompositions:

61 + 31537027 = 31537088
97 + 31536991 = 31537088
151 + 31536937 = 31537088
241 + 31536847 = 31537088
607 + 31536481 = 31537088
691 + 31536397 = 31537088
727 + 31536361 = 31537088
991 + 31536097 = 31537088

Showing the first eight; more decompositions exist.
