Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172846, here are decompositions:

17 + 172829 = 172846
59 + 172787 = 172846
137 + 172709 = 172846
173 + 172673 = 172846
197 + 172649 = 172846
227 + 172619 = 172846
239 + 172607 = 172846
257 + 172589 = 172846

Showing the first eight; more decompositions exist.
