Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17406, here are decompositions:

5 + 17401 = 17406
13 + 17393 = 17406
17 + 17389 = 17406
19 + 17387 = 17406
23 + 17383 = 17406
29 + 17377 = 17406
47 + 17359 = 17406
73 + 17333 = 17406

Showing the first eight; more decompositions exist.
