Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469664, here are decompositions:

11 + 31469653 = 31469664
41 + 31469623 = 31469664
43 + 31469621 = 31469664
101 + 31469563 = 31469664
103 + 31469561 = 31469664
137 + 31469527 = 31469664
151 + 31469513 = 31469664
197 + 31469467 = 31469664

Showing the first eight; more decompositions exist.
