Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499256, here are decompositions:

17 + 31499239 = 31499256
29 + 31499227 = 31499256
67 + 31499189 = 31499256
73 + 31499183 = 31499256
97 + 31499159 = 31499256
149 + 31499107 = 31499256
179 + 31499077 = 31499256
193 + 31499063 = 31499256

Showing the first eight; more decompositions exist.
