Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171898, here are decompositions:

17 + 171881 = 171898
29 + 171869 = 171898
47 + 171851 = 171898
71 + 171827 = 171898
137 + 171761 = 171898
179 + 171719 = 171898
191 + 171707 = 171898
227 + 171671 = 171898

Showing the first eight; more decompositions exist.
