Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469480, here are decompositions:

13 + 31469467 = 31469480
37 + 31469443 = 31469480
73 + 31469407 = 31469480
127 + 31469353 = 31469480
157 + 31469323 = 31469480
181 + 31469299 = 31469480
193 + 31469287 = 31469480
241 + 31469239 = 31469480

Showing the first eight; more decompositions exist.
