Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667500, here are decompositions:

3 + 8667497 = 8667500
43 + 8667457 = 8667500
73 + 8667427 = 8667500
97 + 8667403 = 8667500
151 + 8667349 = 8667500
181 + 8667319 = 8667500
199 + 8667301 = 8667500
211 + 8667289 = 8667500

Showing the first eight; more decompositions exist.
