Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667984, here are decompositions:

5 + 8667979 = 8667984
11 + 8667973 = 8667984
23 + 8667961 = 8667984
53 + 8667931 = 8667984
71 + 8667913 = 8667984
113 + 8667871 = 8667984
137 + 8667847 = 8667984
163 + 8667821 = 8667984

Showing the first eight; more decompositions exist.
