Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13400, here are decompositions:

3 + 13397 = 13400
19 + 13381 = 13400
61 + 13339 = 13400
73 + 13327 = 13400
103 + 13297 = 13400
109 + 13291 = 13400
151 + 13249 = 13400
181 + 13219 = 13400

Showing the first eight; more decompositions exist.
