Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629980, here are decompositions:

17 + 8629963 = 8629980
19 + 8629961 = 8629980
31 + 8629949 = 8629980
53 + 8629927 = 8629980
71 + 8629909 = 8629980
89 + 8629891 = 8629980
97 + 8629883 = 8629980
113 + 8629867 = 8629980

Showing the first eight; more decompositions exist.
