Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617340, here are decompositions:

11 + 31617329 = 31617340
47 + 31617293 = 31617340
59 + 31617281 = 31617340
71 + 31617269 = 31617340
89 + 31617251 = 31617340
101 + 31617239 = 31617340
173 + 31617167 = 31617340
191 + 31617149 = 31617340

Showing the first eight; more decompositions exist.
