Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667998, here are decompositions:

19 + 8667979 = 8667998
37 + 8667961 = 8667998
67 + 8667931 = 8667998
127 + 8667871 = 8667998
151 + 8667847 = 8667998
271 + 8667727 = 8667998
277 + 8667721 = 8667998
337 + 8667661 = 8667998

Showing the first eight; more decompositions exist.
