Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456096, here are decompositions:

3 + 31456093 = 31456096
17 + 31456079 = 31456096
29 + 31456067 = 31456096
83 + 31456013 = 31456096
137 + 31455959 = 31456096
149 + 31455947 = 31456096
167 + 31455929 = 31456096
227 + 31455869 = 31456096

Showing the first eight; more decompositions exist.
