Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576896, here are decompositions:

5 + 31576891 = 31576896
7 + 31576889 = 31576896
53 + 31576843 = 31576896
137 + 31576759 = 31576896
157 + 31576739 = 31576896
193 + 31576703 = 31576896
223 + 31576673 = 31576896
257 + 31576639 = 31576896

Showing the first eight; more decompositions exist.
