Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169860, here are decompositions:

17 + 169843 = 169860
23 + 169837 = 169860
29 + 169831 = 169860
37 + 169823 = 169860
43 + 169817 = 169860
71 + 169789 = 169860
83 + 169777 = 169860
107 + 169753 = 169860

Showing the first eight; more decompositions exist.
