Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172792, here are decompositions:

5 + 172787 = 172792
41 + 172751 = 172792
71 + 172721 = 172792
83 + 172709 = 172792
149 + 172643 = 172792
173 + 172619 = 172792
239 + 172553 = 172792
251 + 172541 = 172792

Showing the first eight; more decompositions exist.
