Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617662, here are decompositions:

3 + 31617659 = 31617662
31 + 31617631 = 31617662
79 + 31617583 = 31617662
103 + 31617559 = 31617662
283 + 31617379 = 31617662
379 + 31617283 = 31617662
409 + 31617253 = 31617662
463 + 31617199 = 31617662

Showing the first eight; more decompositions exist.
