Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169664, here are decompositions:

3 + 169661 = 169664
7 + 169657 = 169664
31 + 169633 = 169664
37 + 169627 = 169664
73 + 169591 = 169664
97 + 169567 = 169664
163 + 169501 = 169664
181 + 169483 = 169664

Showing the first eight; more decompositions exist.
