Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667666, here are decompositions:

5 + 8667661 = 8667666
13 + 8667653 = 8667666
53 + 8667613 = 8667666
103 + 8667563 = 8667666
107 + 8667559 = 8667666
127 + 8667539 = 8667666
239 + 8667427 = 8667666
263 + 8667403 = 8667666

Showing the first eight; more decompositions exist.
