Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667818, here are decompositions:

97 + 8667721 = 8667818
157 + 8667661 = 8667818
307 + 8667511 = 8667818
499 + 8667319 = 8667818
547 + 8667271 = 8667818
739 + 8667079 = 8667818
829 + 8666989 = 8667818
937 + 8666881 = 8667818

Showing the first eight; more decompositions exist.
