Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170870, here are decompositions:

13 + 170857 = 170870
19 + 170851 = 170870
43 + 170827 = 170870
61 + 170809 = 170870
97 + 170773 = 170870
103 + 170767 = 170870
109 + 170761 = 170870
163 + 170707 = 170870

Showing the first eight; more decompositions exist.
