Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171896, here are decompositions:

7 + 171889 = 171896
19 + 171877 = 171896
73 + 171823 = 171896
97 + 171799 = 171896
103 + 171793 = 171896
139 + 171757 = 171896
163 + 171733 = 171896
199 + 171697 = 171896

Showing the first eight; more decompositions exist.
