Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469356, here are decompositions:

3 + 31469353 = 31469356
29 + 31469327 = 31469356
53 + 31469303 = 31469356
179 + 31469177 = 31469356
389 + 31468967 = 31469356
563 + 31468793 = 31469356
599 + 31468757 = 31469356
719 + 31468637 = 31469356

Showing the first eight; more decompositions exist.
