Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617708, here are decompositions:

11 + 31617697 = 31617708
19 + 31617689 = 31617708
29 + 31617679 = 31617708
41 + 31617667 = 31617708
79 + 31617629 = 31617708
149 + 31617559 = 31617708
179 + 31617529 = 31617708
211 + 31617497 = 31617708

Showing the first eight; more decompositions exist.
