Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171756, here are decompositions:

23 + 171733 = 171756
37 + 171719 = 171756
43 + 171713 = 171756
59 + 171697 = 171756
83 + 171673 = 171756
97 + 171659 = 171756
103 + 171653 = 171756
127 + 171629 = 171756

Showing the first eight; more decompositions exist.
