Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171724, here are decompositions:

5 + 171719 = 171724
11 + 171713 = 171724
17 + 171707 = 171724
53 + 171671 = 171724
71 + 171653 = 171724
83 + 171641 = 171724
107 + 171617 = 171724
233 + 171491 = 171724

Showing the first eight; more decompositions exist.
