Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469056, here are decompositions:

23 + 31469033 = 31469056
29 + 31469027 = 31469056
89 + 31468967 = 31469056
137 + 31468919 = 31469056
233 + 31468823 = 31469056
263 + 31468793 = 31469056
389 + 31468667 = 31469056
419 + 31468637 = 31469056

Showing the first eight; more decompositions exist.
