Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617318, here are decompositions:

37 + 31617281 = 31617318
67 + 31617251 = 31617318
79 + 31617239 = 31617318
137 + 31617181 = 31617318
151 + 31617167 = 31617318
241 + 31617077 = 31617318
269 + 31617049 = 31617318
307 + 31617011 = 31617318

Showing the first eight; more decompositions exist.
