Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173506, here are decompositions:

5 + 173501 = 173506
23 + 173483 = 173506
149 + 173357 = 173506
197 + 173309 = 173506
233 + 173273 = 173506
239 + 173267 = 173506
257 + 173249 = 173506
317 + 173189 = 173506

Showing the first eight; more decompositions exist.
