Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617586, here are decompositions:

3 + 31617583 = 31617586
23 + 31617563 = 31617586
53 + 31617533 = 31617586
83 + 31617503 = 31617586
89 + 31617497 = 31617586
137 + 31617449 = 31617586
173 + 31617413 = 31617586
179 + 31617407 = 31617586

Showing the first eight; more decompositions exist.
