Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609680, here are decompositions:

3 + 8609677 = 8609680
11 + 8609669 = 8609680
17 + 8609663 = 8609680
29 + 8609651 = 8609680
41 + 8609639 = 8609680
59 + 8609621 = 8609680
71 + 8609609 = 8609680
83 + 8609597 = 8609680

Showing the first eight; more decompositions exist.
