Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612762, here are decompositions:

3 + 31612759 = 31612762
23 + 31612739 = 31612762
29 + 31612733 = 31612762
101 + 31612661 = 31612762
173 + 31612589 = 31612762
179 + 31612583 = 31612762
281 + 31612481 = 31612762
449 + 31612313 = 31612762

Showing the first eight; more decompositions exist.
