Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537508, here are decompositions:

31 + 31537477 = 31537508
181 + 31537327 = 31537508
199 + 31537309 = 31537508
241 + 31537267 = 31537508
307 + 31537201 = 31537508
421 + 31537087 = 31537508
571 + 31536937 = 31537508
661 + 31536847 = 31537508

Showing the first eight; more decompositions exist.
