Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659218, here are decompositions:

11 + 8659207 = 8659218
37 + 8659181 = 8659218
97 + 8659121 = 8659218
151 + 8659067 = 8659218
157 + 8659061 = 8659218
167 + 8659051 = 8659218
181 + 8659037 = 8659218
199 + 8659019 = 8659218

Showing the first eight; more decompositions exist.
