Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170402, here are decompositions:

13 + 170389 = 170402
19 + 170383 = 170402
31 + 170371 = 170402
61 + 170341 = 170402
103 + 170299 = 170402
109 + 170293 = 170402
139 + 170263 = 170402
163 + 170239 = 170402

Showing the first eight; more decompositions exist.
