Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612424, here are decompositions:

43 + 31612381 = 31612424
61 + 31612363 = 31612424
73 + 31612351 = 31612424
223 + 31612201 = 31612424
541 + 31611883 = 31612424
607 + 31611817 = 31612424
691 + 31611733 = 31612424
751 + 31611673 = 31612424

Showing the first eight; more decompositions exist.
