Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667146, here are decompositions:

43 + 8667103 = 8667146
67 + 8667079 = 8667146
157 + 8666989 = 8667146
193 + 8666953 = 8667146
283 + 8666863 = 8667146
307 + 8666839 = 8667146
337 + 8666809 = 8667146
349 + 8666797 = 8667146

Showing the first eight; more decompositions exist.
