Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609664, here are decompositions:

13 + 8609651 = 8609664
17 + 8609647 = 8609664
43 + 8609621 = 8609664
47 + 8609617 = 8609664
53 + 8609611 = 8609664
67 + 8609597 = 8609664
73 + 8609591 = 8609664
83 + 8609581 = 8609664

Showing the first eight; more decompositions exist.
