Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667366, here are decompositions:

17 + 8667349 = 8667366
47 + 8667319 = 8667366
53 + 8667313 = 8667366
67 + 8667299 = 8667366
109 + 8667257 = 8667366
139 + 8667227 = 8667366
199 + 8667167 = 8667366
229 + 8667137 = 8667366

Showing the first eight; more decompositions exist.
