Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612996, here are decompositions:

5 + 31612991 = 31612996
83 + 31612913 = 31612996
257 + 31612739 = 31612996
263 + 31612733 = 31612996
269 + 31612727 = 31612996
449 + 31612547 = 31612996
509 + 31612487 = 31612996
683 + 31612313 = 31612996

Showing the first eight; more decompositions exist.
