Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469666, here are decompositions:

13 + 31469653 = 31469666
37 + 31469629 = 31469666
43 + 31469623 = 31469666
79 + 31469587 = 31469666
97 + 31469569 = 31469666
103 + 31469563 = 31469666
139 + 31469527 = 31469666
199 + 31469467 = 31469666

Showing the first eight; more decompositions exist.
