Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612514, here are decompositions:

61 + 31612453 = 31612514
151 + 31612363 = 31612514
163 + 31612351 = 31612514
313 + 31612201 = 31612514
433 + 31612081 = 31612514
607 + 31611907 = 31612514
631 + 31611883 = 31612514
673 + 31611841 = 31612514

Showing the first eight; more decompositions exist.
