Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171726, here are decompositions:

7 + 171719 = 171726
13 + 171713 = 171726
19 + 171707 = 171726
29 + 171697 = 171726
47 + 171679 = 171726
53 + 171673 = 171726
67 + 171659 = 171726
73 + 171653 = 171726

Showing the first eight; more decompositions exist.
