Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990222, here are decompositions:

11 + 990211 = 990222
41 + 990181 = 990222
43 + 990179 = 990222
53 + 990169 = 990222
59 + 990163 = 990222
71 + 990151 = 990222
179 + 990043 = 990222
199 + 990023 = 990222

Showing the first eight; more decompositions exist.
