Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667216, here are decompositions:

37 + 8667179 = 8667216
79 + 8667137 = 8667216
113 + 8667103 = 8667216
137 + 8667079 = 8667216
223 + 8666993 = 8667216
227 + 8666989 = 8667216
263 + 8666953 = 8667216
277 + 8666939 = 8667216

Showing the first eight; more decompositions exist.
