Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659404, here are decompositions:

11 + 8659393 = 8659404
23 + 8659381 = 8659404
41 + 8659363 = 8659404
53 + 8659351 = 8659404
181 + 8659223 = 8659404
197 + 8659207 = 8659404
223 + 8659181 = 8659404
251 + 8659153 = 8659404

Showing the first eight; more decompositions exist.
