Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537460, here are decompositions:

151 + 31537309 = 31537460
193 + 31537267 = 31537460
307 + 31537153 = 31537460
313 + 31537147 = 31537460
373 + 31537087 = 31537460
421 + 31537039 = 31537460
433 + 31537027 = 31537460
457 + 31537003 = 31537460

Showing the first eight; more decompositions exist.
