Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659138, here are decompositions:

17 + 8659121 = 8659138
41 + 8659097 = 8659138
71 + 8659067 = 8659138
101 + 8659037 = 8659138
149 + 8658989 = 8659138
179 + 8658959 = 8659138
197 + 8658941 = 8659138
227 + 8658911 = 8659138

Showing the first eight; more decompositions exist.
