Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667920, here are decompositions:

7 + 8667913 = 8667920
13 + 8667907 = 8667920
73 + 8667847 = 8667920
127 + 8667793 = 8667920
193 + 8667727 = 8667920
199 + 8667721 = 8667920
223 + 8667697 = 8667920
307 + 8667613 = 8667920

Showing the first eight; more decompositions exist.
