Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667822, here are decompositions:

13 + 8667809 = 8667822
29 + 8667793 = 8667822
89 + 8667733 = 8667822
101 + 8667721 = 8667822
181 + 8667641 = 8667822
211 + 8667611 = 8667822
263 + 8667559 = 8667822
283 + 8667539 = 8667822

Showing the first eight; more decompositions exist.
