Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612012, here are decompositions:

71 + 31611941 = 31612012
101 + 31611911 = 31612012
251 + 31611761 = 31612012
293 + 31611719 = 31612012
353 + 31611659 = 31612012
431 + 31611581 = 31612012
503 + 31611509 = 31612012
683 + 31611329 = 31612012

Showing the first eight; more decompositions exist.
