Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173018, here are decompositions:

19 + 172999 = 173018
31 + 172987 = 173018
37 + 172981 = 173018
151 + 172867 = 173018
211 + 172807 = 173018
277 + 172741 = 173018
331 + 172687 = 173018
337 + 172681 = 173018

Showing the first eight; more decompositions exist.
