Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667880, here are decompositions:

17 + 8667863 = 8667880
59 + 8667821 = 8667880
71 + 8667809 = 8667880
83 + 8667797 = 8667880
173 + 8667707 = 8667880
191 + 8667689 = 8667880
227 + 8667653 = 8667880
239 + 8667641 = 8667880

Showing the first eight; more decompositions exist.
