Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607264, here are decompositions:

37 + 31607227 = 31607264
127 + 31607137 = 31607264
163 + 31607101 = 31607264
307 + 31606957 = 31607264
313 + 31606951 = 31607264
523 + 31606741 = 31607264
607 + 31606657 = 31607264
613 + 31606651 = 31607264

Showing the first eight; more decompositions exist.
