Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169398, here are decompositions:

29 + 169369 = 169398
37 + 169361 = 169398
59 + 169339 = 169398
71 + 169327 = 169398
79 + 169319 = 169398
139 + 169259 = 169398
149 + 169249 = 169398
157 + 169241 = 169398

Showing the first eight; more decompositions exist.
