Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617726, here are decompositions:

13 + 31617713 = 31617726
29 + 31617697 = 31617726
37 + 31617689 = 31617726
47 + 31617679 = 31617726
53 + 31617673 = 31617726
59 + 31617667 = 31617726
67 + 31617659 = 31617726
97 + 31617629 = 31617726

Showing the first eight; more decompositions exist.
