Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612924, here are decompositions:

11 + 31612913 = 31612924
71 + 31612853 = 31612924
191 + 31612733 = 31612924
197 + 31612727 = 31612924
257 + 31612667 = 31612924
263 + 31612661 = 31612924
443 + 31612481 = 31612924
617 + 31612307 = 31612924

Showing the first eight; more decompositions exist.
