Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622178, here are decompositions:

41 + 8622137 = 8622178
107 + 8622071 = 8622178
137 + 8622041 = 8622178
167 + 8622011 = 8622178
239 + 8621939 = 8622178
251 + 8621927 = 8622178
281 + 8621897 = 8622178
311 + 8621867 = 8622178

Showing the first eight; more decompositions exist.
