Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617332, here are decompositions:

3 + 31617329 = 31617332
79 + 31617253 = 31617332
151 + 31617181 = 31617332
199 + 31617133 = 31617332
283 + 31617049 = 31617332
661 + 31616671 = 31617332
709 + 31616623 = 31617332
811 + 31616521 = 31617332

Showing the first eight; more decompositions exist.
