Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647712, here are decompositions:

13 + 8647699 = 8647712
181 + 8647531 = 8647712
211 + 8647501 = 8647712
439 + 8647273 = 8647712
691 + 8647021 = 8647712
751 + 8646961 = 8647712
769 + 8646943 = 8647712
823 + 8646889 = 8647712

Showing the first eight; more decompositions exist.
