Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469968, here are decompositions:

107 + 31469861 = 31469968
227 + 31469741 = 31469968
347 + 31469621 = 31469968
389 + 31469579 = 31469968
449 + 31469519 = 31469968
521 + 31469447 = 31469968
557 + 31469411 = 31469968
641 + 31469327 = 31469968

Showing the first eight; more decompositions exist.
