Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456176, here are decompositions:

13 + 31456163 = 31456176
53 + 31456123 = 31456176
83 + 31456093 = 31456176
97 + 31456079 = 31456176
109 + 31456067 = 31456176
163 + 31456013 = 31456176
173 + 31456003 = 31456176
229 + 31455947 = 31456176

Showing the first eight; more decompositions exist.
