Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655724, here are decompositions:

3 + 8655721 = 8655724
5 + 8655719 = 8655724
17 + 8655707 = 8655724
23 + 8655701 = 8655724
47 + 8655677 = 8655724
53 + 8655671 = 8655724
71 + 8655653 = 8655724
83 + 8655641 = 8655724

Showing the first eight; more decompositions exist.
