Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667222, here are decompositions:

43 + 8667179 = 8667222
71 + 8667151 = 8667222
101 + 8667121 = 8667222
229 + 8666993 = 8667222
233 + 8666989 = 8667222
269 + 8666953 = 8667222
283 + 8666939 = 8667222
331 + 8666891 = 8667222

Showing the first eight; more decompositions exist.
