Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671978, here are decompositions:

11 + 8671967 = 8671978
41 + 8671937 = 8671978
59 + 8671919 = 8671978
71 + 8671907 = 8671978
167 + 8671811 = 8671978
239 + 8671739 = 8671978
257 + 8671721 = 8671978
269 + 8671709 = 8671978

Showing the first eight; more decompositions exist.
