Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612610, here are decompositions:

13 + 31612597 = 31612610
37 + 31612573 = 31612610
79 + 31612531 = 31612610
97 + 31612513 = 31612610
157 + 31612453 = 31612610
181 + 31612429 = 31612610
229 + 31612381 = 31612610
241 + 31612369 = 31612610

Showing the first eight; more decompositions exist.
