Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596992, here are decompositions:

43 + 31596949 = 31596992
79 + 31596913 = 31596992
103 + 31596889 = 31596992
109 + 31596883 = 31596992
199 + 31596793 = 31596992
223 + 31596769 = 31596992
241 + 31596751 = 31596992
283 + 31596709 = 31596992

Showing the first eight; more decompositions exist.
