Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12228, here are decompositions:

17 + 12211 = 12228
31 + 12197 = 12228
67 + 12161 = 12228
71 + 12157 = 12228
79 + 12149 = 12228
109 + 12119 = 12228
127 + 12101 = 12228
131 + 12097 = 12228

Showing the first eight; more decompositions exist.
