Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612118, here are decompositions:

37 + 31612081 = 31612118
211 + 31611907 = 31612118
277 + 31611841 = 31612118
409 + 31611709 = 31612118
541 + 31611577 = 31612118
631 + 31611487 = 31612118
661 + 31611457 = 31612118
739 + 31611379 = 31612118

Showing the first eight; more decompositions exist.
