Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609918, here are decompositions:

7 + 8609911 = 8609918
19 + 8609899 = 8609918
127 + 8609791 = 8609918
199 + 8609719 = 8609918
241 + 8609677 = 8609918
271 + 8609647 = 8609918
307 + 8609611 = 8609918
337 + 8609581 = 8609918

Showing the first eight; more decompositions exist.
