Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639080, here are decompositions:

17 + 8639063 = 8639080
29 + 8639051 = 8639080
53 + 8639027 = 8639080
83 + 8638997 = 8639080
89 + 8638991 = 8639080
113 + 8638967 = 8639080
227 + 8638853 = 8639080
347 + 8638733 = 8639080

Showing the first eight; more decompositions exist.
