Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659240, here are decompositions:

17 + 8659223 = 8659240
59 + 8659181 = 8659240
173 + 8659067 = 8659240
179 + 8659061 = 8659240
197 + 8659043 = 8659240
251 + 8658989 = 8659240
257 + 8658983 = 8659240
263 + 8658977 = 8659240

Showing the first eight; more decompositions exist.
