Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170786, here are decompositions:

13 + 170773 = 170786
19 + 170767 = 170786
37 + 170749 = 170786
79 + 170707 = 170786
97 + 170689 = 170786
139 + 170647 = 170786
229 + 170557 = 170786
277 + 170509 = 170786

Showing the first eight; more decompositions exist.
