Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617638, here are decompositions:

11 + 8617627 = 8617638
89 + 8617549 = 8617638
191 + 8617447 = 8617638
199 + 8617439 = 8617638
241 + 8617397 = 8617638
257 + 8617381 = 8617638
277 + 8617361 = 8617638
311 + 8617327 = 8617638

Showing the first eight; more decompositions exist.
