Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469516, here are decompositions:

3 + 31469513 = 31469516
73 + 31469443 = 31469516
109 + 31469407 = 31469516
163 + 31469353 = 31469516
193 + 31469323 = 31469516
223 + 31469293 = 31469516
229 + 31469287 = 31469516
277 + 31469239 = 31469516

Showing the first eight; more decompositions exist.
