Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667978, here are decompositions:

5 + 8667973 = 8667978
17 + 8667961 = 8667978
29 + 8667949 = 8667978
47 + 8667931 = 8667978
71 + 8667907 = 8667978
79 + 8667899 = 8667978
107 + 8667871 = 8667978
131 + 8667847 = 8667978

Showing the first eight; more decompositions exist.
