Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609772, here are decompositions:

19 + 8609753 = 8609772
43 + 8609729 = 8609772
53 + 8609719 = 8609772
89 + 8609683 = 8609772
103 + 8609669 = 8609772
109 + 8609663 = 8609772
151 + 8609621 = 8609772
163 + 8609609 = 8609772

Showing the first eight; more decompositions exist.
