Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667886, here are decompositions:

23 + 8667863 = 8667886
89 + 8667797 = 8667886
179 + 8667707 = 8667886
197 + 8667689 = 8667886
233 + 8667653 = 8667886
347 + 8667539 = 8667886
389 + 8667497 = 8667886
467 + 8667419 = 8667886

Showing the first eight; more decompositions exist.
