Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617178, here are decompositions:

7 + 8617171 = 8617178
181 + 8616997 = 8617178
277 + 8616901 = 8617178
397 + 8616781 = 8617178
421 + 8616757 = 8617178
457 + 8616721 = 8617178
487 + 8616691 = 8617178
499 + 8616679 = 8617178

Showing the first eight; more decompositions exist.
