Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617366, here are decompositions:

5 + 31617361 = 31617366
37 + 31617329 = 31617366
73 + 31617293 = 31617366
83 + 31617283 = 31617366
97 + 31617269 = 31617366
113 + 31617253 = 31617366
127 + 31617239 = 31617366
167 + 31617199 = 31617366

Showing the first eight; more decompositions exist.
