Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469256, here are decompositions:

17 + 31469239 = 31469256
47 + 31469209 = 31469256
59 + 31469197 = 31469256
79 + 31469177 = 31469256
113 + 31469143 = 31469256
223 + 31469033 = 31469256
229 + 31469027 = 31469256
263 + 31468993 = 31469256

Showing the first eight; more decompositions exist.
