Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169768, here are decompositions:

17 + 169751 = 169768
59 + 169709 = 169768
101 + 169667 = 169768
107 + 169661 = 169768
311 + 169457 = 169768
359 + 169409 = 169768
449 + 169319 = 169768
461 + 169307 = 169768

Showing the first eight; more decompositions exist.
