Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596828, here are decompositions:

7 + 31596821 = 31596828
31 + 31596797 = 31596828
59 + 31596769 = 31596828
71 + 31596757 = 31596828
79 + 31596749 = 31596828
149 + 31596679 = 31596828
157 + 31596671 = 31596828
167 + 31596661 = 31596828

Showing the first eight; more decompositions exist.
