Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169904, here are decompositions:

13 + 169891 = 169904
61 + 169843 = 169904
67 + 169837 = 169904
73 + 169831 = 169904
127 + 169777 = 169904
151 + 169753 = 169904
211 + 169693 = 169904
223 + 169681 = 169904

Showing the first eight; more decompositions exist.
