Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469498, here are decompositions:

31 + 31469467 = 31469498
199 + 31469299 = 31469498
211 + 31469287 = 31469498
367 + 31469131 = 31469498
397 + 31469101 = 31469498
457 + 31469041 = 31469498
1051 + 31468447 = 31469498
1129 + 31468369 = 31469498

Showing the first eight; more decompositions exist.
