Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612792, here are decompositions:

53 + 31612739 = 31612792
59 + 31612733 = 31612792
131 + 31612661 = 31612792
173 + 31612619 = 31612792
311 + 31612481 = 31612792
401 + 31612391 = 31612792
479 + 31612313 = 31612792
569 + 31612223 = 31612792

Showing the first eight; more decompositions exist.
