Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667166, here are decompositions:

29 + 8667137 = 8667166
173 + 8666993 = 8667166
227 + 8666939 = 8667166
239 + 8666927 = 8667166
317 + 8666849 = 8667166
359 + 8666807 = 8667166
383 + 8666783 = 8667166
419 + 8666747 = 8667166

Showing the first eight; more decompositions exist.
