Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173512, here are decompositions:

11 + 173501 = 173512
29 + 173483 = 173512
83 + 173429 = 173512
239 + 173273 = 173512
263 + 173249 = 173512
293 + 173219 = 173512
431 + 173081 = 173512
491 + 173021 = 173512

Showing the first eight; more decompositions exist.
