Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622218, here are decompositions:

211 + 8622007 = 8622218
229 + 8621989 = 8622218
271 + 8621947 = 8622218
307 + 8621911 = 8622218
349 + 8621869 = 8622218
421 + 8621797 = 8622218
439 + 8621779 = 8622218
541 + 8621677 = 8622218

Showing the first eight; more decompositions exist.
