Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529126, here are decompositions:

19 + 31529107 = 31529126
37 + 31529089 = 31529126
73 + 31529053 = 31529126
157 + 31528969 = 31529126
283 + 31528843 = 31529126
313 + 31528813 = 31529126
397 + 31528729 = 31529126
457 + 31528669 = 31529126

Showing the first eight; more decompositions exist.
