Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171744, here are decompositions:

11 + 171733 = 171744
31 + 171713 = 171744
37 + 171707 = 171744
47 + 171697 = 171744
71 + 171673 = 171744
73 + 171671 = 171744
103 + 171641 = 171744
107 + 171637 = 171744

Showing the first eight; more decompositions exist.
