Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171996, here are decompositions:

59 + 171937 = 171996
67 + 171929 = 171996
73 + 171923 = 171996
79 + 171917 = 171996
107 + 171889 = 171996
127 + 171869 = 171996
173 + 171823 = 171996
193 + 171803 = 171996

Showing the first eight; more decompositions exist.
