Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469448, here are decompositions:

5 + 31469443 = 31469448
7 + 31469441 = 31469448
37 + 31469411 = 31469448
41 + 31469407 = 31469448
61 + 31469387 = 31469448
149 + 31469299 = 31469448
239 + 31469209 = 31469448
251 + 31469197 = 31469448

Showing the first eight; more decompositions exist.
