Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671166, here are decompositions:

19 + 8671147 = 8671166
67 + 8671099 = 8671166
103 + 8671063 = 8671166
109 + 8671057 = 8671166
157 + 8671009 = 8671166
223 + 8670943 = 8671166
457 + 8670709 = 8671166
463 + 8670703 = 8671166

Showing the first eight; more decompositions exist.
