Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469588, here are decompositions:

19 + 31469569 = 31469588
61 + 31469527 = 31469588
181 + 31469407 = 31469588
349 + 31469239 = 31469588
379 + 31469209 = 31469588
457 + 31469131 = 31469588
487 + 31469101 = 31469588
547 + 31469041 = 31469588

Showing the first eight; more decompositions exist.
