Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469318, here are decompositions:

19 + 31469299 = 31469318
31 + 31469287 = 31469318
79 + 31469239 = 31469318
109 + 31469209 = 31469318
277 + 31469041 = 31469318
457 + 31468861 = 31469318
541 + 31468777 = 31469318
619 + 31468699 = 31469318

Showing the first eight; more decompositions exist.
