Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631250, here are decompositions:

3 + 8631247 = 8631250
59 + 8631191 = 8631250
83 + 8631167 = 8631250
167 + 8631083 = 8631250
227 + 8631023 = 8631250
233 + 8631017 = 8631250
239 + 8631011 = 8631250
347 + 8630903 = 8631250

Showing the first eight; more decompositions exist.
