Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647250, here are decompositions:

19 + 8647231 = 8647250
67 + 8647183 = 8647250
127 + 8647123 = 8647250
223 + 8647027 = 8647250
229 + 8647021 = 8647250
307 + 8646943 = 8647250
397 + 8646853 = 8647250
433 + 8646817 = 8647250

Showing the first eight; more decompositions exist.
