Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529264, here are decompositions:

7 + 31529257 = 31529264
97 + 31529167 = 31529264
157 + 31529107 = 31529264
211 + 31529053 = 31529264
271 + 31528993 = 31529264
421 + 31528843 = 31529264
433 + 31528831 = 31529264
457 + 31528807 = 31529264

Showing the first eight; more decompositions exist.
