Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576996, here are decompositions:

5 + 31576991 = 31576996
29 + 31576967 = 31576996
47 + 31576949 = 31576996
107 + 31576889 = 31576996
257 + 31576739 = 31576996
293 + 31576703 = 31576996
467 + 31576529 = 31576996
557 + 31576439 = 31576996

Showing the first eight; more decompositions exist.
