Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667720, here are decompositions:

13 + 8667707 = 8667720
23 + 8667697 = 8667720
31 + 8667689 = 8667720
43 + 8667677 = 8667720
59 + 8667661 = 8667720
67 + 8667653 = 8667720
79 + 8667641 = 8667720
107 + 8667613 = 8667720

Showing the first eight; more decompositions exist.
