Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667646, here are decompositions:

5 + 8667641 = 8667646
83 + 8667563 = 8667646
107 + 8667539 = 8667646
149 + 8667497 = 8667646
227 + 8667419 = 8667646
233 + 8667413 = 8667646
269 + 8667377 = 8667646
347 + 8667299 = 8667646

Showing the first eight; more decompositions exist.
