Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667878, here are decompositions:

7 + 8667871 = 8667878
31 + 8667847 = 8667878
151 + 8667727 = 8667878
157 + 8667721 = 8667878
181 + 8667697 = 8667878
277 + 8667601 = 8667878
367 + 8667511 = 8667878
421 + 8667457 = 8667878

Showing the first eight; more decompositions exist.
