Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612846, here are decompositions:

107 + 31612739 = 31612846
113 + 31612733 = 31612846
179 + 31612667 = 31612846
227 + 31612619 = 31612846
257 + 31612589 = 31612846
263 + 31612583 = 31612846
359 + 31612487 = 31612846
569 + 31612277 = 31612846

Showing the first eight; more decompositions exist.
