Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659278, here are decompositions:

59 + 8659219 = 8659278
71 + 8659207 = 8659278
97 + 8659181 = 8659278
157 + 8659121 = 8659278
179 + 8659099 = 8659278
181 + 8659097 = 8659278
211 + 8659067 = 8659278
227 + 8659051 = 8659278

Showing the first eight; more decompositions exist.
