Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609658, here are decompositions:

7 + 8609651 = 8609658
11 + 8609647 = 8609658
19 + 8609639 = 8609658
37 + 8609621 = 8609658
41 + 8609617 = 8609658
47 + 8609611 = 8609658
61 + 8609597 = 8609658
67 + 8609591 = 8609658

Showing the first eight; more decompositions exist.
