Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170398, here are decompositions:

5 + 170393 = 170398
29 + 170369 = 170398
47 + 170351 = 170398
71 + 170327 = 170398
131 + 170267 = 170398
149 + 170249 = 170398
167 + 170231 = 170398
191 + 170207 = 170398

Showing the first eight; more decompositions exist.
