Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469404, here are decompositions:

17 + 31469387 = 31469404
47 + 31469357 = 31469404
101 + 31469303 = 31469404
227 + 31469177 = 31469404
503 + 31468901 = 31469404
647 + 31468757 = 31469404
677 + 31468727 = 31469404
773 + 31468631 = 31469404

Showing the first eight; more decompositions exist.
