Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671966, here are decompositions:

29 + 8671937 = 8671966
47 + 8671919 = 8671966
59 + 8671907 = 8671966
197 + 8671769 = 8671966
227 + 8671739 = 8671966
257 + 8671709 = 8671966
269 + 8671697 = 8671966
383 + 8671583 = 8671966

Showing the first eight; more decompositions exist.
