Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617570, here are decompositions:

7 + 31617563 = 31617570
11 + 31617559 = 31617570
37 + 31617533 = 31617570
41 + 31617529 = 31617570
67 + 31617503 = 31617570
73 + 31617497 = 31617570
109 + 31617461 = 31617570
113 + 31617457 = 31617570

Showing the first eight; more decompositions exist.
