Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667198, here are decompositions:

19 + 8667179 = 8667198
31 + 8667167 = 8667198
47 + 8667151 = 8667198
61 + 8667137 = 8667198
271 + 8666927 = 8667198
307 + 8666891 = 8667198
317 + 8666881 = 8667198
349 + 8666849 = 8667198

Showing the first eight; more decompositions exist.
