Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609660, here are decompositions:

13 + 8609647 = 8609660
43 + 8609617 = 8609660
79 + 8609581 = 8609660
97 + 8609563 = 8609660
127 + 8609533 = 8609660
211 + 8609449 = 8609660
229 + 8609431 = 8609660
307 + 8609353 = 8609660

Showing the first eight; more decompositions exist.
