Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169390, here are decompositions:

17 + 169373 = 169390
29 + 169361 = 169390
47 + 169343 = 169390
71 + 169319 = 169390
83 + 169307 = 169390
107 + 169283 = 169390
131 + 169259 = 169390
149 + 169241 = 169390

Showing the first eight; more decompositions exist.
