Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667944, here are decompositions:

13 + 8667931 = 8667944
31 + 8667913 = 8667944
37 + 8667907 = 8667944
73 + 8667871 = 8667944
97 + 8667847 = 8667944
151 + 8667793 = 8667944
211 + 8667733 = 8667944
223 + 8667721 = 8667944

Showing the first eight; more decompositions exist.
