Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111222, here are decompositions:

5 + 111217 = 111222
11 + 111211 = 111222
31 + 111191 = 111222
73 + 111149 = 111222
79 + 111143 = 111222
101 + 111121 = 111222
103 + 111119 = 111222
113 + 111109 = 111222

Showing the first eight; more decompositions exist.
