Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617246, here are decompositions:

7 + 31617239 = 31617246
47 + 31617199 = 31617246
79 + 31617167 = 31617246
97 + 31617149 = 31617246
113 + 31617133 = 31617246
173 + 31617073 = 31617246
197 + 31617049 = 31617246
223 + 31617023 = 31617246

Showing the first eight; more decompositions exist.
