Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469600, here are decompositions:

13 + 31469587 = 31469600
31 + 31469569 = 31469600
37 + 31469563 = 31469600
73 + 31469527 = 31469600
157 + 31469443 = 31469600
193 + 31469407 = 31469600
277 + 31469323 = 31469600
307 + 31469293 = 31469600

Showing the first eight; more decompositions exist.
