Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169380, here are decompositions:

7 + 169373 = 169380
11 + 169369 = 169380
19 + 169361 = 169380
37 + 169343 = 169380
41 + 169339 = 169380
53 + 169327 = 169380
59 + 169321 = 169380
61 + 169319 = 169380

Showing the first eight; more decompositions exist.
