Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170738, here are decompositions:

31 + 170707 = 170738
37 + 170701 = 170738
97 + 170641 = 170738
181 + 170557 = 170738
199 + 170539 = 170738
229 + 170509 = 170738
241 + 170497 = 170738
349 + 170389 = 170738

Showing the first eight; more decompositions exist.
