Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496456, here are decompositions:

7 + 31496449 = 31496456
37 + 31496419 = 31496456
67 + 31496389 = 31496456
127 + 31496329 = 31496456
139 + 31496317 = 31496456
163 + 31496293 = 31496456
193 + 31496263 = 31496456
283 + 31496173 = 31496456

Showing the first eight; more decompositions exist.
