Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617604, here are decompositions:

17 + 31617587 = 31617604
41 + 31617563 = 31617604
71 + 31617533 = 31617604
101 + 31617503 = 31617604
107 + 31617497 = 31617604
173 + 31617431 = 31617604
191 + 31617413 = 31617604
197 + 31617407 = 31617604

Showing the first eight; more decompositions exist.
