Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576096, here are decompositions:

5 + 31576091 = 31576096
29 + 31576067 = 31576096
47 + 31576049 = 31576096
59 + 31576037 = 31576096
89 + 31576007 = 31576096
173 + 31575923 = 31576096
179 + 31575917 = 31576096
197 + 31575899 = 31576096

Showing the first eight; more decompositions exist.
