Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512634, here are decompositions:

3 + 31512631 = 31512634
17 + 31512617 = 31512634
47 + 31512587 = 31512634
113 + 31512521 = 31512634
443 + 31512191 = 31512634
521 + 31512113 = 31512634
563 + 31512071 = 31512634
617 + 31512017 = 31512634

Showing the first eight; more decompositions exist.
