Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667756, here are decompositions:

23 + 8667733 = 8667756
29 + 8667727 = 8667756
59 + 8667697 = 8667756
67 + 8667689 = 8667756
79 + 8667677 = 8667756
103 + 8667653 = 8667756
193 + 8667563 = 8667756
197 + 8667559 = 8667756

Showing the first eight; more decompositions exist.
