Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169928, here are decompositions:

19 + 169909 = 169928
37 + 169891 = 169928
97 + 169831 = 169928
139 + 169789 = 169928
151 + 169777 = 169928
271 + 169657 = 169928
337 + 169591 = 169928
397 + 169531 = 169928

Showing the first eight; more decompositions exist.
