Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171984, here are decompositions:

37 + 171947 = 171984
47 + 171937 = 171984
61 + 171923 = 171984
67 + 171917 = 171984
103 + 171881 = 171984
107 + 171877 = 171984
157 + 171827 = 171984
173 + 171811 = 171984

Showing the first eight; more decompositions exist.
