Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646222, here are decompositions:

41 + 8646181 = 8646222
59 + 8646163 = 8646222
103 + 8646119 = 8646222
163 + 8646059 = 8646222
241 + 8645981 = 8646222
251 + 8645971 = 8646222
281 + 8645941 = 8646222
359 + 8645863 = 8646222

Showing the first eight; more decompositions exist.
