Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647172, here are decompositions:

43 + 8647129 = 8647172
109 + 8647063 = 8647172
151 + 8647021 = 8647172
211 + 8646961 = 8647172
223 + 8646949 = 8647172
229 + 8646943 = 8647172
283 + 8646889 = 8647172
349 + 8646823 = 8647172

Showing the first eight; more decompositions exist.
