Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617744, here are decompositions:

31 + 31617713 = 31617744
47 + 31617697 = 31617744
71 + 31617673 = 31617744
113 + 31617631 = 31617744
157 + 31617587 = 31617744
181 + 31617563 = 31617744
211 + 31617533 = 31617744
241 + 31617503 = 31617744

Showing the first eight; more decompositions exist.
