Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667930, here are decompositions:

17 + 8667913 = 8667930
23 + 8667907 = 8667930
31 + 8667899 = 8667930
59 + 8667871 = 8667930
67 + 8667863 = 8667930
83 + 8667847 = 8667930
101 + 8667829 = 8667930
109 + 8667821 = 8667930

Showing the first eight; more decompositions exist.
