Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17400, here are decompositions:

7 + 17393 = 17400
11 + 17389 = 17400
13 + 17387 = 17400
17 + 17383 = 17400
23 + 17377 = 17400
41 + 17359 = 17400
59 + 17341 = 17400
67 + 17333 = 17400

Showing the first eight; more decompositions exist.
