Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617496, here are decompositions:

3 + 31617493 = 31617496
47 + 31617449 = 31617496
83 + 31617413 = 31617496
89 + 31617407 = 31617496
167 + 31617329 = 31617496
227 + 31617269 = 31617496
257 + 31617239 = 31617496
347 + 31617149 = 31617496

Showing the first eight; more decompositions exist.
