Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172810, here are decompositions:

3 + 172807 = 172810
23 + 172787 = 172810
59 + 172751 = 172810
89 + 172721 = 172810
101 + 172709 = 172810
137 + 172673 = 172810
167 + 172643 = 172810
191 + 172619 = 172810

Showing the first eight; more decompositions exist.
