Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469398, here are decompositions:

11 + 31469387 = 31469398
41 + 31469357 = 31469398
71 + 31469327 = 31469398
431 + 31468967 = 31469398
479 + 31468919 = 31469398
641 + 31468757 = 31469398
761 + 31468637 = 31469398
809 + 31468589 = 31469398

Showing the first eight; more decompositions exist.
