Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612822, here are decompositions:

83 + 31612739 = 31612822
89 + 31612733 = 31612822
233 + 31612589 = 31612822
239 + 31612583 = 31612822
431 + 31612391 = 31612822
509 + 31612313 = 31612822
599 + 31612223 = 31612822
701 + 31612121 = 31612822

Showing the first eight; more decompositions exist.
