Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617800, here are decompositions:

13 + 8617787 = 8617800
31 + 8617769 = 8617800
47 + 8617753 = 8617800
97 + 8617703 = 8617800
101 + 8617699 = 8617800
173 + 8617627 = 8617800
239 + 8617561 = 8617800
251 + 8617549 = 8617800

Showing the first eight; more decompositions exist.
