Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469606, here are decompositions:

19 + 31469587 = 31469606
37 + 31469569 = 31469606
43 + 31469563 = 31469606
79 + 31469527 = 31469606
139 + 31469467 = 31469606
163 + 31469443 = 31469606
199 + 31469407 = 31469606
283 + 31469323 = 31469606

Showing the first eight; more decompositions exist.
