Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675128, here are decompositions:

17 + 8675111 = 8675128
29 + 8675099 = 8675128
101 + 8675027 = 8675128
107 + 8675021 = 8675128
167 + 8674961 = 8675128
191 + 8674937 = 8675128
227 + 8674901 = 8675128
239 + 8674889 = 8675128

Showing the first eight; more decompositions exist.
