Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617782, here are decompositions:

13 + 8617769 = 8617782
29 + 8617753 = 8617782
79 + 8617703 = 8617782
83 + 8617699 = 8617782
101 + 8617681 = 8617782
233 + 8617549 = 8617782
263 + 8617519 = 8617782
269 + 8617513 = 8617782

Showing the first eight; more decompositions exist.
