Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589664, here are decompositions:

5 + 31589659 = 31589664
31 + 31589633 = 31589664
53 + 31589611 = 31589664
97 + 31589567 = 31589664
103 + 31589561 = 31589664
151 + 31589513 = 31589664
181 + 31589483 = 31589664
191 + 31589473 = 31589664

Showing the first eight; more decompositions exist.
