Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666822, here are decompositions:

13 + 8666809 = 8666822
139 + 8666683 = 8666822
331 + 8666491 = 8666822
379 + 8666443 = 8666822
499 + 8666323 = 8666822
823 + 8665999 = 8666822
883 + 8665939 = 8666822
1171 + 8665651 = 8666822

Showing the first eight; more decompositions exist.
