Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469026, here are decompositions:

59 + 31468967 = 31469026
107 + 31468919 = 31469026
233 + 31468793 = 31469026
269 + 31468757 = 31469026
359 + 31468667 = 31469026
389 + 31468637 = 31469026
467 + 31468559 = 31469026
503 + 31468523 = 31469026

Showing the first eight; more decompositions exist.
