Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469934, here are decompositions:

11 + 31469923 = 31469934
31 + 31469903 = 31469934
73 + 31469861 = 31469934
137 + 31469797 = 31469934
151 + 31469783 = 31469934
173 + 31469761 = 31469934
193 + 31469741 = 31469934
211 + 31469723 = 31469934

Showing the first eight; more decompositions exist.
