Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659266, here are decompositions:

23 + 8659243 = 8659266
43 + 8659223 = 8659266
47 + 8659219 = 8659266
59 + 8659207 = 8659266
113 + 8659153 = 8659266
167 + 8659099 = 8659266
199 + 8659067 = 8659266
223 + 8659043 = 8659266

Showing the first eight; more decompositions exist.
