Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596920, here are decompositions:

7 + 31596913 = 31596920
13 + 31596907 = 31596920
31 + 31596889 = 31596920
37 + 31596883 = 31596920
73 + 31596847 = 31596920
127 + 31596793 = 31596920
151 + 31596769 = 31596920
163 + 31596757 = 31596920

Showing the first eight; more decompositions exist.
