Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647066, here are decompositions:

3 + 8647063 = 8647066
5 + 8647061 = 8647066
23 + 8647043 = 8647066
59 + 8647007 = 8647066
137 + 8646929 = 8647066
167 + 8646899 = 8647066
347 + 8646719 = 8647066
359 + 8646707 = 8647066

Showing the first eight; more decompositions exist.
