Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469570, here are decompositions:

7 + 31469563 = 31469570
43 + 31469527 = 31469570
103 + 31469467 = 31469570
127 + 31469443 = 31469570
163 + 31469407 = 31469570
271 + 31469299 = 31469570
277 + 31469293 = 31469570
283 + 31469287 = 31469570

Showing the first eight; more decompositions exist.
