Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617294, here are decompositions:

11 + 31617283 = 31617294
13 + 31617281 = 31617294
41 + 31617253 = 31617294
43 + 31617251 = 31617294
113 + 31617181 = 31617294
127 + 31617167 = 31617294
193 + 31617101 = 31617294
271 + 31617023 = 31617294

Showing the first eight; more decompositions exist.
