Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469556, here are decompositions:

29 + 31469527 = 31469556
37 + 31469519 = 31469556
43 + 31469513 = 31469556
89 + 31469467 = 31469556
109 + 31469447 = 31469556
113 + 31469443 = 31469556
149 + 31469407 = 31469556
199 + 31469357 = 31469556

Showing the first eight; more decompositions exist.
