Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17500, here are decompositions:

3 + 17497 = 17500
11 + 17489 = 17500
17 + 17483 = 17500
23 + 17477 = 17500
29 + 17471 = 17500
83 + 17417 = 17500
107 + 17393 = 17500
113 + 17387 = 17500

Showing the first eight; more decompositions exist.
