Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567136, here are decompositions:

157 + 31566979 = 31567136
163 + 31566973 = 31567136
373 + 31566763 = 31567136
547 + 31566589 = 31567136
577 + 31566559 = 31567136
613 + 31566523 = 31567136
619 + 31566517 = 31567136
709 + 31566427 = 31567136

Showing the first eight; more decompositions exist.
