Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612668, here are decompositions:

5 + 31612663 = 31612668
7 + 31612661 = 31612668
41 + 31612627 = 31612668
47 + 31612621 = 31612668
71 + 31612597 = 31612668
79 + 31612589 = 31612668
137 + 31612531 = 31612668
181 + 31612487 = 31612668

Showing the first eight; more decompositions exist.
