Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171964, here are decompositions:

17 + 171947 = 171964
41 + 171923 = 171964
47 + 171917 = 171964
83 + 171881 = 171964
101 + 171863 = 171964
113 + 171851 = 171964
137 + 171827 = 171964
251 + 171713 = 171964

Showing the first eight; more decompositions exist.
