Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172726, here are decompositions:

5 + 172721 = 172726
17 + 172709 = 172726
53 + 172673 = 172726
83 + 172643 = 172726
107 + 172619 = 172726
137 + 172589 = 172726
173 + 172553 = 172726
293 + 172433 = 172726

Showing the first eight; more decompositions exist.
