Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609724, here are decompositions:

5 + 8609719 = 8609724
37 + 8609687 = 8609724
41 + 8609683 = 8609724
47 + 8609677 = 8609724
61 + 8609663 = 8609724
73 + 8609651 = 8609724
103 + 8609621 = 8609724
107 + 8609617 = 8609724

Showing the first eight; more decompositions exist.
