Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617702, here are decompositions:

5 + 31617697 = 31617702
13 + 31617689 = 31617702
23 + 31617679 = 31617702
29 + 31617673 = 31617702
43 + 31617659 = 31617702
71 + 31617631 = 31617702
73 + 31617629 = 31617702
139 + 31617563 = 31617702

Showing the first eight; more decompositions exist.
