Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171960, here are decompositions:

13 + 171947 = 171960
23 + 171937 = 171960
31 + 171929 = 171960
37 + 171923 = 171960
43 + 171917 = 171960
71 + 171889 = 171960
79 + 171881 = 171960
83 + 171877 = 171960

Showing the first eight; more decompositions exist.
