Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671806, here are decompositions:

37 + 8671769 = 8671806
67 + 8671739 = 8671806
97 + 8671709 = 8671806
109 + 8671697 = 8671806
137 + 8671669 = 8671806
167 + 8671639 = 8671806
173 + 8671633 = 8671806
223 + 8671583 = 8671806

Showing the first eight; more decompositions exist.
