Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469486, here are decompositions:

19 + 31469467 = 31469486
43 + 31469443 = 31469486
79 + 31469407 = 31469486
163 + 31469323 = 31469486
193 + 31469293 = 31469486
199 + 31469287 = 31469486
277 + 31469209 = 31469486
523 + 31468963 = 31469486

Showing the first eight; more decompositions exist.
