Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668724, here are decompositions:

3 + 8668721 = 8668724
13 + 8668711 = 8668724
37 + 8668687 = 8668724
223 + 8668501 = 8668724
241 + 8668483 = 8668724
367 + 8668357 = 8668724
457 + 8668267 = 8668724
523 + 8668201 = 8668724

Showing the first eight; more decompositions exist.
