Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13280, here are decompositions:

13 + 13267 = 13280
31 + 13249 = 13280
61 + 13219 = 13280
97 + 13183 = 13280
103 + 13177 = 13280
109 + 13171 = 13280
181 + 13099 = 13280
271 + 13009 = 13280

Showing the first eight; more decompositions exist.
