Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609980, here are decompositions:

17 + 8609963 = 8609980
53 + 8609927 = 8609980
89 + 8609891 = 8609980
101 + 8609879 = 8609980
131 + 8609849 = 8609980
167 + 8609813 = 8609980
227 + 8609753 = 8609980
251 + 8609729 = 8609980

Showing the first eight; more decompositions exist.
