Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622212, here are decompositions:

3 + 8622209 = 8622212
211 + 8622001 = 8622212
223 + 8621989 = 8622212
229 + 8621983 = 8622212
241 + 8621971 = 8622212
349 + 8621863 = 8622212
433 + 8621779 = 8622212
439 + 8621773 = 8622212

Showing the first eight; more decompositions exist.
