Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469710, here are decompositions:

89 + 31469621 = 31469710
131 + 31469579 = 31469710
149 + 31469561 = 31469710
179 + 31469531 = 31469710
191 + 31469519 = 31469710
197 + 31469513 = 31469710
263 + 31469447 = 31469710
269 + 31469441 = 31469710

Showing the first eight; more decompositions exist.
