Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469338, here are decompositions:

11 + 31469327 = 31469338
59 + 31469279 = 31469338
269 + 31469069 = 31469338
311 + 31469027 = 31469338
419 + 31468919 = 31469338
701 + 31468637 = 31469338
809 + 31468529 = 31469338
821 + 31468517 = 31469338

Showing the first eight; more decompositions exist.
