Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617804, here are decompositions:

7 + 31617797 = 31617804
41 + 31617763 = 31617804
47 + 31617757 = 31617804
107 + 31617697 = 31617804
131 + 31617673 = 31617804
137 + 31617667 = 31617804
173 + 31617631 = 31617804
241 + 31617563 = 31617804

Showing the first eight; more decompositions exist.
