Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105222, here are decompositions:

11 + 105211 = 105222
23 + 105199 = 105222
79 + 105143 = 105222
151 + 105071 = 105222
191 + 105031 = 105222
199 + 105023 = 105222
223 + 104999 = 105222
251 + 104971 = 105222

Showing the first eight; more decompositions exist.
