Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667840, here are decompositions:

11 + 8667829 = 8667840
19 + 8667821 = 8667840
31 + 8667809 = 8667840
43 + 8667797 = 8667840
47 + 8667793 = 8667840
107 + 8667733 = 8667840
113 + 8667727 = 8667840
151 + 8667689 = 8667840

Showing the first eight; more decompositions exist.
