Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609688, here are decompositions:

5 + 8609683 = 8609688
11 + 8609677 = 8609688
19 + 8609669 = 8609688
37 + 8609651 = 8609688
41 + 8609647 = 8609688
67 + 8609621 = 8609688
71 + 8609617 = 8609688
79 + 8609609 = 8609688

Showing the first eight; more decompositions exist.
