Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522222, here are decompositions:

11 + 522211 = 522222
23 + 522199 = 522222
31 + 522191 = 522222
61 + 522161 = 522222
109 + 522113 = 522222
139 + 522083 = 522222
149 + 522073 = 522222
163 + 522059 = 522222

Showing the first eight; more decompositions exist.
