Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31664, here are decompositions:

7 + 31657 = 31664
37 + 31627 = 31664
97 + 31567 = 31664
151 + 31513 = 31664
271 + 31393 = 31664
277 + 31387 = 31664
307 + 31357 = 31664
331 + 31333 = 31664

Showing the first eight; more decompositions exist.
