Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126222, here are decompositions:

11 + 126211 = 126222
23 + 126199 = 126222
71 + 126151 = 126222
79 + 126143 = 126222
181 + 126041 = 126222
191 + 126031 = 126222
199 + 126023 = 126222
211 + 126011 = 126222

Showing the first eight; more decompositions exist.
