Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654724, here are decompositions:

11 + 8654713 = 8654724
61 + 8654663 = 8654724
83 + 8654641 = 8654724
103 + 8654621 = 8654724
107 + 8654617 = 8654724
151 + 8654573 = 8654724
181 + 8654543 = 8654724
241 + 8654483 = 8654724

Showing the first eight; more decompositions exist.
