Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169790, here are decompositions:

7 + 169783 = 169790
13 + 169777 = 169790
37 + 169753 = 169790
97 + 169693 = 169790
109 + 169681 = 169790
151 + 169639 = 169790
157 + 169633 = 169790
163 + 169627 = 169790

Showing the first eight; more decompositions exist.
