Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646724, here are decompositions:

3 + 8646721 = 8646724
5 + 8646719 = 8646724
17 + 8646707 = 8646724
41 + 8646683 = 8646724
227 + 8646497 = 8646724
347 + 8646377 = 8646724
431 + 8646293 = 8646724
467 + 8646257 = 8646724

Showing the first eight; more decompositions exist.
