Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612460, here are decompositions:

7 + 31612453 = 31612460
31 + 31612429 = 31612460
37 + 31612423 = 31612460
79 + 31612381 = 31612460
97 + 31612363 = 31612460
109 + 31612351 = 31612460
151 + 31612309 = 31612460
379 + 31612081 = 31612460

Showing the first eight; more decompositions exist.
