Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469194, here are decompositions:

17 + 31469177 = 31469194
167 + 31469027 = 31469194
227 + 31468967 = 31469194
293 + 31468901 = 31469194
401 + 31468793 = 31469194
467 + 31468727 = 31469194
557 + 31468637 = 31469194
563 + 31468631 = 31469194

Showing the first eight; more decompositions exist.
