Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724, here are decompositions:

5 + 8719 = 8724
11 + 8713 = 8724
17 + 8707 = 8724
31 + 8693 = 8724
43 + 8681 = 8724
47 + 8677 = 8724
61 + 8663 = 8724
83 + 8641 = 8724

Showing the first eight; more decompositions exist.
