Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617634, here are decompositions:

3 + 31617631 = 31617634
5 + 31617629 = 31617634
47 + 31617587 = 31617634
71 + 31617563 = 31617634
101 + 31617533 = 31617634
131 + 31617503 = 31617634
137 + 31617497 = 31617634
173 + 31617461 = 31617634

Showing the first eight; more decompositions exist.
