Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469408, here are decompositions:

109 + 31469299 = 31469408
199 + 31469209 = 31469408
211 + 31469197 = 31469408
277 + 31469131 = 31469408
307 + 31469101 = 31469408
367 + 31469041 = 31469408
547 + 31468861 = 31469408
631 + 31468777 = 31469408

Showing the first eight; more decompositions exist.
