Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17428, here are decompositions:

11 + 17417 = 17428
41 + 17387 = 17428
101 + 17327 = 17428
107 + 17321 = 17428
137 + 17291 = 17428
197 + 17231 = 17428
239 + 17189 = 17428
269 + 17159 = 17428

Showing the first eight; more decompositions exist.
