Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172822, here are decompositions:

71 + 172751 = 172822
101 + 172721 = 172822
113 + 172709 = 172822
149 + 172673 = 172822
173 + 172649 = 172822
179 + 172643 = 172822
233 + 172589 = 172822
239 + 172583 = 172822

Showing the first eight; more decompositions exist.
