Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529074, here are decompositions:

107 + 31528967 = 31529074
233 + 31528841 = 31529074
251 + 31528823 = 31529074
263 + 31528811 = 31529074
461 + 31528613 = 31529074
641 + 31528433 = 31529074
701 + 31528373 = 31529074
761 + 31528313 = 31529074

Showing the first eight; more decompositions exist.
