Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667980, here are decompositions:

7 + 8667973 = 8667980
19 + 8667961 = 8667980
31 + 8667949 = 8667980
67 + 8667913 = 8667980
73 + 8667907 = 8667980
109 + 8667871 = 8667980
151 + 8667829 = 8667980
283 + 8667697 = 8667980

Showing the first eight; more decompositions exist.
