Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13328, here are decompositions:

19 + 13309 = 13328
31 + 13297 = 13328
37 + 13291 = 13328
61 + 13267 = 13328
79 + 13249 = 13328
109 + 13219 = 13328
151 + 13177 = 13328
157 + 13171 = 13328

Showing the first eight; more decompositions exist.
