Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171846, here are decompositions:

19 + 171827 = 171846
23 + 171823 = 171846
43 + 171803 = 171846
47 + 171799 = 171846
53 + 171793 = 171846
83 + 171763 = 171846
89 + 171757 = 171846
113 + 171733 = 171846

Showing the first eight; more decompositions exist.
