Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171952, here are decompositions:

5 + 171947 = 171952
23 + 171929 = 171952
29 + 171923 = 171952
71 + 171881 = 171952
83 + 171869 = 171952
89 + 171863 = 171952
101 + 171851 = 171952
149 + 171803 = 171952

Showing the first eight; more decompositions exist.
