Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659656, here are decompositions:

13 + 8659643 = 8659656
29 + 8659627 = 8659656
67 + 8659589 = 8659656
97 + 8659559 = 8659656
113 + 8659543 = 8659656
193 + 8659463 = 8659656
199 + 8659457 = 8659656
233 + 8659423 = 8659656

Showing the first eight; more decompositions exist.
