Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617806, here are decompositions:

7 + 8617799 = 8617806
19 + 8617787 = 8617806
37 + 8617769 = 8617806
53 + 8617753 = 8617806
103 + 8617703 = 8617806
107 + 8617699 = 8617806
179 + 8617627 = 8617806
257 + 8617549 = 8617806

Showing the first eight; more decompositions exist.
