Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671768, here are decompositions:

29 + 8671739 = 8671768
47 + 8671721 = 8671768
59 + 8671709 = 8671768
71 + 8671697 = 8671768
137 + 8671631 = 8671768
179 + 8671589 = 8671768
251 + 8671517 = 8671768
257 + 8671511 = 8671768

Showing the first eight; more decompositions exist.
