Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622220, here are decompositions:

11 + 8622209 = 8622220
29 + 8622191 = 8622220
83 + 8622137 = 8622220
107 + 8622113 = 8622220
149 + 8622071 = 8622220
179 + 8622041 = 8622220
197 + 8622023 = 8622220
281 + 8621939 = 8622220

Showing the first eight; more decompositions exist.
