Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667512, here are decompositions:

109 + 8667403 = 8667512
163 + 8667349 = 8667512
193 + 8667319 = 8667512
199 + 8667313 = 8667512
211 + 8667301 = 8667512
223 + 8667289 = 8667512
241 + 8667271 = 8667512
409 + 8667103 = 8667512

Showing the first eight; more decompositions exist.
