Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647244, here are decompositions:

13 + 8647231 = 8647244
61 + 8647183 = 8647244
181 + 8647063 = 8647244
223 + 8647021 = 8647244
283 + 8646961 = 8647244
421 + 8646823 = 8647244
523 + 8646721 = 8647244
577 + 8646667 = 8647244

Showing the first eight; more decompositions exist.
