Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659212, here are decompositions:

5 + 8659207 = 8659212
31 + 8659181 = 8659212
59 + 8659153 = 8659212
113 + 8659099 = 8659212
151 + 8659061 = 8659212
193 + 8659019 = 8659212
223 + 8658989 = 8659212
229 + 8658983 = 8659212

Showing the first eight; more decompositions exist.
