Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671810, here are decompositions:

41 + 8671769 = 8671810
71 + 8671739 = 8671810
89 + 8671721 = 8671810
101 + 8671709 = 8671810
113 + 8671697 = 8671810
179 + 8671631 = 8671810
227 + 8671583 = 8671810
293 + 8671517 = 8671810

Showing the first eight; more decompositions exist.
