Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469534, here are decompositions:

3 + 31469531 = 31469534
7 + 31469527 = 31469534
67 + 31469467 = 31469534
127 + 31469407 = 31469534
181 + 31469353 = 31469534
211 + 31469323 = 31469534
241 + 31469293 = 31469534
337 + 31469197 = 31469534

Showing the first eight; more decompositions exist.
