Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171894, here are decompositions:

5 + 171889 = 171894
13 + 171881 = 171894
17 + 171877 = 171894
31 + 171863 = 171894
43 + 171851 = 171894
67 + 171827 = 171894
71 + 171823 = 171894
83 + 171811 = 171894

Showing the first eight; more decompositions exist.
