Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469706, here are decompositions:

17 + 31469689 = 31469706
53 + 31469653 = 31469706
83 + 31469623 = 31469706
127 + 31469579 = 31469706
137 + 31469569 = 31469706
179 + 31469527 = 31469706
193 + 31469513 = 31469706
239 + 31469467 = 31469706

Showing the first eight; more decompositions exist.
