Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613822, here are decompositions:

5 + 8613817 = 8613822
11 + 8613811 = 8613822
13 + 8613809 = 8613822
71 + 8613751 = 8613822
79 + 8613743 = 8613822
83 + 8613739 = 8613822
89 + 8613733 = 8613822
199 + 8613623 = 8613822

Showing the first eight; more decompositions exist.
