Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596896, here are decompositions:

7 + 31596889 = 31596896
13 + 31596883 = 31596896
103 + 31596793 = 31596896
127 + 31596769 = 31596896
139 + 31596757 = 31596896
223 + 31596673 = 31596896
283 + 31596613 = 31596896
313 + 31596583 = 31596896

Showing the first eight; more decompositions exist.
