Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469510, here are decompositions:

43 + 31469467 = 31469510
67 + 31469443 = 31469510
103 + 31469407 = 31469510
157 + 31469353 = 31469510
211 + 31469299 = 31469510
223 + 31469287 = 31469510
271 + 31469239 = 31469510
313 + 31469197 = 31469510

Showing the first eight; more decompositions exist.
