Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609656, here are decompositions:

5 + 8609651 = 8609656
17 + 8609639 = 8609656
47 + 8609609 = 8609656
59 + 8609597 = 8609656
173 + 8609483 = 8609656
179 + 8609477 = 8609656
197 + 8609459 = 8609656
347 + 8609309 = 8609656

Showing the first eight; more decompositions exist.
