Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667942, here are decompositions:

11 + 8667931 = 8667942
13 + 8667929 = 8667942
29 + 8667913 = 8667942
43 + 8667899 = 8667942
71 + 8667871 = 8667942
79 + 8667863 = 8667942
113 + 8667829 = 8667942
149 + 8667793 = 8667942

Showing the first eight; more decompositions exist.
