Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622238, here are decompositions:

29 + 8622209 = 8622238
47 + 8622191 = 8622238
101 + 8622137 = 8622238
167 + 8622071 = 8622238
197 + 8622041 = 8622238
227 + 8622011 = 8622238
311 + 8621927 = 8622238
419 + 8621819 = 8622238

Showing the first eight; more decompositions exist.
