Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612256, here are decompositions:

349 + 31611907 = 31612256
373 + 31611883 = 31612256
439 + 31611817 = 31612256
499 + 31611757 = 31612256
523 + 31611733 = 31612256
547 + 31611709 = 31612256
673 + 31611583 = 31612256
769 + 31611487 = 31612256

Showing the first eight; more decompositions exist.
