Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667884, here are decompositions:

13 + 8667871 = 8667884
37 + 8667847 = 8667884
151 + 8667733 = 8667884
157 + 8667727 = 8667884
163 + 8667721 = 8667884
223 + 8667661 = 8667884
271 + 8667613 = 8667884
283 + 8667601 = 8667884

Showing the first eight; more decompositions exist.
