Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646722, here are decompositions:

3 + 8646719 = 8646722
13 + 8646709 = 8646722
151 + 8646571 = 8646722
163 + 8646559 = 8646722
193 + 8646529 = 8646722
211 + 8646511 = 8646722
463 + 8646259 = 8646722
499 + 8646223 = 8646722

Showing the first eight; more decompositions exist.
