Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728724, here are decompositions:

3 + 8728721 = 8728724
7 + 8728717 = 8728724
13 + 8728711 = 8728724
61 + 8728663 = 8728724
97 + 8728627 = 8728724
127 + 8728597 = 8728724
211 + 8728513 = 8728724
241 + 8728483 = 8728724

Showing the first eight; more decompositions exist.
