Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667188, here are decompositions:

37 + 8667151 = 8667188
67 + 8667121 = 8667188
109 + 8667079 = 8667188
199 + 8666989 = 8667188
307 + 8666881 = 8667188
349 + 8666839 = 8667188
379 + 8666809 = 8667188
421 + 8666767 = 8667188

Showing the first eight; more decompositions exist.
