Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609668, here are decompositions:

5 + 8609663 = 8609668
17 + 8609651 = 8609668
29 + 8609639 = 8609668
47 + 8609621 = 8609668
59 + 8609609 = 8609668
71 + 8609597 = 8609668
167 + 8609501 = 8609668
191 + 8609477 = 8609668

Showing the first eight; more decompositions exist.
