Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596980, here are decompositions:

3 + 31596977 = 31596980
31 + 31596949 = 31596980
67 + 31596913 = 31596980
73 + 31596907 = 31596980
97 + 31596883 = 31596980
211 + 31596769 = 31596980
223 + 31596757 = 31596980
229 + 31596751 = 31596980

Showing the first eight; more decompositions exist.
