Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617422, here are decompositions:

13 + 31617409 = 31617422
19 + 31617403 = 31617422
43 + 31617379 = 31617422
61 + 31617361 = 31617422
139 + 31617283 = 31617422
223 + 31617199 = 31617422
241 + 31617181 = 31617422
349 + 31617073 = 31617422

Showing the first eight; more decompositions exist.
