Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622166, here are decompositions:

29 + 8622137 = 8622166
53 + 8622113 = 8622166
149 + 8622017 = 8622166
227 + 8621939 = 8622166
233 + 8621933 = 8622166
239 + 8621927 = 8622166
269 + 8621897 = 8622166
347 + 8621819 = 8622166

Showing the first eight; more decompositions exist.
