Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612346, here are decompositions:

37 + 31612309 = 31612346
277 + 31612069 = 31612346
349 + 31611997 = 31612346
439 + 31611907 = 31612346
463 + 31611883 = 31612346
613 + 31611733 = 31612346
643 + 31611703 = 31612346
673 + 31611673 = 31612346

Showing the first eight; more decompositions exist.
