Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169678, here are decompositions:

11 + 169667 = 169678
17 + 169661 = 169678
29 + 169649 = 169678
71 + 169607 = 169678
251 + 169427 = 169678
269 + 169409 = 169678
317 + 169361 = 169678
359 + 169319 = 169678

Showing the first eight; more decompositions exist.
