Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667744, here are decompositions:

11 + 8667733 = 8667744
17 + 8667727 = 8667744
23 + 8667721 = 8667744
37 + 8667707 = 8667744
47 + 8667697 = 8667744
67 + 8667677 = 8667744
83 + 8667661 = 8667744
103 + 8667641 = 8667744

Showing the first eight; more decompositions exist.
