Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612984, here are decompositions:

3 + 31612981 = 31612984
23 + 31612961 = 31612984
71 + 31612913 = 31612984
131 + 31612853 = 31612984
251 + 31612733 = 31612984
257 + 31612727 = 31612984
317 + 31612667 = 31612984
401 + 31612583 = 31612984

Showing the first eight; more decompositions exist.
