Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945222, here are decompositions:

11 + 945211 = 945222
13 + 945209 = 945222
43 + 945179 = 945222
71 + 945151 = 945222
79 + 945143 = 945222
163 + 945059 = 945222
191 + 945031 = 945222
269 + 944953 = 945222

Showing the first eight; more decompositions exist.
