Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622286, here are decompositions:

149 + 8622137 = 8622286
173 + 8622113 = 8622286
263 + 8622023 = 8622286
269 + 8622017 = 8622286
347 + 8621939 = 8622286
353 + 8621933 = 8622286
359 + 8621927 = 8622286
389 + 8621897 = 8622286

Showing the first eight; more decompositions exist.
