Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671822, here are decompositions:

11 + 8671811 = 8671822
53 + 8671769 = 8671822
83 + 8671739 = 8671822
101 + 8671721 = 8671822
113 + 8671709 = 8671822
191 + 8671631 = 8671822
233 + 8671589 = 8671822
239 + 8671583 = 8671822

Showing the first eight; more decompositions exist.
