Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596996, here are decompositions:

5 + 31596991 = 31596996
19 + 31596977 = 31596996
47 + 31596949 = 31596996
73 + 31596923 = 31596996
83 + 31596913 = 31596996
89 + 31596907 = 31596996
97 + 31596899 = 31596996
107 + 31596889 = 31596996

Showing the first eight; more decompositions exist.
