Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667938, here are decompositions:

7 + 8667931 = 8667938
31 + 8667907 = 8667938
67 + 8667871 = 8667938
109 + 8667829 = 8667938
211 + 8667727 = 8667938
241 + 8667697 = 8667938
277 + 8667661 = 8667938
337 + 8667601 = 8667938

Showing the first eight; more decompositions exist.
