Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469948, here are decompositions:

151 + 31469797 = 31469948
277 + 31469671 = 31469948
379 + 31469569 = 31469948
421 + 31469527 = 31469948
541 + 31469407 = 31469948
661 + 31469287 = 31469948
709 + 31469239 = 31469948
739 + 31469209 = 31469948

Showing the first eight; more decompositions exist.
