Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617766, here are decompositions:

3 + 31617763 = 31617766
53 + 31617713 = 31617766
107 + 31617659 = 31617766
137 + 31617629 = 31617766
179 + 31617587 = 31617766
233 + 31617533 = 31617766
263 + 31617503 = 31617766
269 + 31617497 = 31617766

Showing the first eight; more decompositions exist.
