Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13228, here are decompositions:

11 + 13217 = 13228
41 + 13187 = 13228
101 + 13127 = 13228
107 + 13121 = 13228
179 + 13049 = 13228
191 + 13037 = 13228
227 + 13001 = 13228
269 + 12959 = 13228

Showing the first eight; more decompositions exist.
