Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626222, here are decompositions:

41 + 8626181 = 8626222
53 + 8626169 = 8626222
83 + 8626139 = 8626222
113 + 8626109 = 8626222
179 + 8626043 = 8626222
239 + 8625983 = 8626222
263 + 8625959 = 8626222
389 + 8625833 = 8626222

Showing the first eight; more decompositions exist.
