Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667918, here are decompositions:

5 + 8667913 = 8667918
11 + 8667907 = 8667918
19 + 8667899 = 8667918
47 + 8667871 = 8667918
71 + 8667847 = 8667918
89 + 8667829 = 8667918
97 + 8667821 = 8667918
109 + 8667809 = 8667918

Showing the first eight; more decompositions exist.
