Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641166, here are decompositions:

19 + 8641147 = 8641166
73 + 8641093 = 8641166
103 + 8641063 = 8641166
199 + 8640967 = 8641166
277 + 8640889 = 8641166
283 + 8640883 = 8641166
307 + 8640859 = 8641166
349 + 8640817 = 8641166

Showing the first eight; more decompositions exist.
