Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469514, here are decompositions:

47 + 31469467 = 31469514
67 + 31469447 = 31469514
71 + 31469443 = 31469514
73 + 31469441 = 31469514
103 + 31469411 = 31469514
107 + 31469407 = 31469514
127 + 31469387 = 31469514
157 + 31469357 = 31469514

Showing the first eight; more decompositions exist.
