Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593996, here are decompositions:

13 + 31593983 = 31593996
37 + 31593959 = 31593996
43 + 31593953 = 31593996
53 + 31593943 = 31593996
59 + 31593937 = 31593996
127 + 31593869 = 31593996
157 + 31593839 = 31593996
163 + 31593833 = 31593996

Showing the first eight; more decompositions exist.
