Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647222, here are decompositions:

29 + 8647193 = 8647222
41 + 8647181 = 8647222
83 + 8647139 = 8647222
131 + 8647091 = 8647222
179 + 8647043 = 8647222
191 + 8647031 = 8647222
251 + 8646971 = 8647222
293 + 8646929 = 8647222

Showing the first eight; more decompositions exist.
