Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173500, here are decompositions:

3 + 173497 = 173500
17 + 173483 = 173500
71 + 173429 = 173500
191 + 173309 = 173500
227 + 173273 = 173500
233 + 173267 = 173500
251 + 173249 = 173500
281 + 173219 = 173500

Showing the first eight; more decompositions exist.
