Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022222, here are decompositions:

13 + 1022209 = 1022222
31 + 1022191 = 1022222
43 + 1022179 = 1022222
109 + 1022113 = 1022222
139 + 1022083 = 1022222
151 + 1022071 = 1022222
163 + 1022059 = 1022222
211 + 1022011 = 1022222

Showing the first eight; more decompositions exist.
