Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667724, here are decompositions:

3 + 8667721 = 8667724
17 + 8667707 = 8667724
47 + 8667677 = 8667724
71 + 8667653 = 8667724
83 + 8667641 = 8667724
113 + 8667611 = 8667724
227 + 8667497 = 8667724
293 + 8667431 = 8667724

Showing the first eight; more decompositions exist.
