Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647212, here are decompositions:

19 + 8647193 = 8647212
29 + 8647183 = 8647212
31 + 8647181 = 8647212
73 + 8647139 = 8647212
83 + 8647129 = 8647212
89 + 8647123 = 8647212
149 + 8647063 = 8647212
151 + 8647061 = 8647212

Showing the first eight; more decompositions exist.
