Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617660, here are decompositions:

29 + 31617631 = 31617660
31 + 31617629 = 31617660
73 + 31617587 = 31617660
97 + 31617563 = 31617660
101 + 31617559 = 31617660
127 + 31617533 = 31617660
131 + 31617529 = 31617660
157 + 31617503 = 31617660

Showing the first eight; more decompositions exist.
