Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617770, here are decompositions:

7 + 31617763 = 31617770
13 + 31617757 = 31617770
73 + 31617697 = 31617770
97 + 31617673 = 31617770
103 + 31617667 = 31617770
139 + 31617631 = 31617770
211 + 31617559 = 31617770
241 + 31617529 = 31617770

Showing the first eight; more decompositions exist.
