Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469630, here are decompositions:

7 + 31469623 = 31469630
43 + 31469587 = 31469630
61 + 31469569 = 31469630
67 + 31469563 = 31469630
103 + 31469527 = 31469630
163 + 31469467 = 31469630
223 + 31469407 = 31469630
277 + 31469353 = 31469630

Showing the first eight; more decompositions exist.
