Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172858, here are decompositions:

5 + 172853 = 172858
29 + 172829 = 172858
71 + 172787 = 172858
107 + 172751 = 172858
137 + 172721 = 172858
149 + 172709 = 172858
239 + 172619 = 172858
251 + 172607 = 172858

Showing the first eight; more decompositions exist.
