Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469546, here are decompositions:

19 + 31469527 = 31469546
79 + 31469467 = 31469546
103 + 31469443 = 31469546
139 + 31469407 = 31469546
193 + 31469353 = 31469546
223 + 31469323 = 31469546
307 + 31469239 = 31469546
337 + 31469209 = 31469546

Showing the first eight; more decompositions exist.
