Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624864, here are decompositions:

43 + 8624821 = 8624864
151 + 8624713 = 8624864
541 + 8624323 = 8624864
613 + 8624251 = 8624864
643 + 8624221 = 8624864
673 + 8624191 = 8624864
727 + 8624137 = 8624864
733 + 8624131 = 8624864

Showing the first eight; more decompositions exist.
