Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564096, here are decompositions:

17 + 31564079 = 31564096
107 + 31563989 = 31564096
149 + 31563947 = 31564096
167 + 31563929 = 31564096
197 + 31563899 = 31564096
233 + 31563863 = 31564096
269 + 31563827 = 31564096
359 + 31563737 = 31564096

Showing the first eight; more decompositions exist.
