Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612130, here are decompositions:

61 + 31612069 = 31612130
223 + 31611907 = 31612130
313 + 31611817 = 31612130
373 + 31611757 = 31612130
397 + 31611733 = 31612130
421 + 31611709 = 31612130
457 + 31611673 = 31612130
463 + 31611667 = 31612130

Showing the first eight; more decompositions exist.
