Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469926, here are decompositions:

3 + 31469923 = 31469926
23 + 31469903 = 31469926
113 + 31469813 = 31469926
347 + 31469579 = 31469926
479 + 31469447 = 31469926
503 + 31469423 = 31469926
569 + 31469357 = 31469926
599 + 31469327 = 31469926

Showing the first eight; more decompositions exist.
