Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617356, here are decompositions:

73 + 31617283 = 31617356
103 + 31617253 = 31617356
157 + 31617199 = 31617356
223 + 31617133 = 31617356
283 + 31617073 = 31617356
307 + 31617049 = 31617356
439 + 31616917 = 31617356
499 + 31616857 = 31617356

Showing the first eight; more decompositions exist.
