Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617342, here are decompositions:

13 + 31617329 = 31617342
59 + 31617283 = 31617342
61 + 31617281 = 31617342
73 + 31617269 = 31617342
89 + 31617253 = 31617342
103 + 31617239 = 31617342
193 + 31617149 = 31617342
241 + 31617101 = 31617342

Showing the first eight; more decompositions exist.
