Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612760, here are decompositions:

7 + 31612753 = 31612760
13 + 31612747 = 31612760
31 + 31612729 = 31612760
97 + 31612663 = 31612760
139 + 31612621 = 31612760
163 + 31612597 = 31612760
229 + 31612531 = 31612760
307 + 31612453 = 31612760

Showing the first eight; more decompositions exist.
