Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172750, here are decompositions:

29 + 172721 = 172750
41 + 172709 = 172750
101 + 172649 = 172750
107 + 172643 = 172750
131 + 172619 = 172750
167 + 172583 = 172750
197 + 172553 = 172750
233 + 172517 = 172750

Showing the first eight; more decompositions exist.
