Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103228, here are decompositions:

11 + 103217 = 103228
137 + 103091 = 103228
149 + 103079 = 103228
179 + 103049 = 103228
227 + 103001 = 103228
317 + 102911 = 103228
347 + 102881 = 103228
431 + 102797 = 103228

Showing the first eight; more decompositions exist.
