Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667158, here are decompositions:

7 + 8667151 = 8667158
37 + 8667121 = 8667158
79 + 8667079 = 8667158
277 + 8666881 = 8667158
349 + 8666809 = 8667158
727 + 8666431 = 8667158
739 + 8666419 = 8667158
811 + 8666347 = 8667158

Showing the first eight; more decompositions exist.
