Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667138, here are decompositions:

17 + 8667121 = 8667138
59 + 8667079 = 8667138
149 + 8666989 = 8667138
199 + 8666939 = 8667138
211 + 8666927 = 8667138
257 + 8666881 = 8667138
331 + 8666807 = 8667138
457 + 8666681 = 8667138

Showing the first eight; more decompositions exist.
