Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171884, here are decompositions:

3 + 171881 = 171884
7 + 171877 = 171884
61 + 171823 = 171884
73 + 171811 = 171884
127 + 171757 = 171884
151 + 171733 = 171884
211 + 171673 = 171884
313 + 171571 = 171884

Showing the first eight; more decompositions exist.
