Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469882, here are decompositions:

151 + 31469731 = 31469882
193 + 31469689 = 31469882
211 + 31469671 = 31469882
229 + 31469653 = 31469882
313 + 31469569 = 31469882
439 + 31469443 = 31469882
643 + 31469239 = 31469882
673 + 31469209 = 31469882

Showing the first eight; more decompositions exist.
