Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726724, here are decompositions:

11 + 8726713 = 8726724
37 + 8726687 = 8726724
47 + 8726677 = 8726724
53 + 8726671 = 8726724
113 + 8726611 = 8726724
137 + 8726587 = 8726724
151 + 8726573 = 8726724
191 + 8726533 = 8726724

Showing the first eight; more decompositions exist.
