Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617736, here are decompositions:

23 + 31617713 = 31617736
47 + 31617689 = 31617736
107 + 31617629 = 31617736
149 + 31617587 = 31617736
173 + 31617563 = 31617736
233 + 31617503 = 31617736
239 + 31617497 = 31617736
443 + 31617293 = 31617736

Showing the first eight; more decompositions exist.
