Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507264, here are decompositions:

53 + 31507211 = 31507264
83 + 31507181 = 31507264
227 + 31507037 = 31507264
353 + 31506911 = 31507264
443 + 31506821 = 31507264
521 + 31506743 = 31507264
587 + 31506677 = 31507264
743 + 31506521 = 31507264

Showing the first eight; more decompositions exist.
