Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617854, here are decompositions:

43 + 31617811 = 31617854
97 + 31617757 = 31617854
157 + 31617697 = 31617854
181 + 31617673 = 31617854
223 + 31617631 = 31617854
271 + 31617583 = 31617854
397 + 31617457 = 31617854
571 + 31617283 = 31617854

Showing the first eight; more decompositions exist.
