Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639118, here are decompositions:

11 + 8639107 = 8639118
29 + 8639089 = 8639118
67 + 8639051 = 8639118
107 + 8639011 = 8639118
127 + 8638991 = 8639118
151 + 8638967 = 8639118
167 + 8638951 = 8639118
181 + 8638937 = 8639118

Showing the first eight; more decompositions exist.
