Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469914, here are decompositions:

11 + 31469903 = 31469914
53 + 31469861 = 31469914
101 + 31469813 = 31469914
131 + 31469783 = 31469914
173 + 31469741 = 31469914
191 + 31469723 = 31469914
293 + 31469621 = 31469914
353 + 31469561 = 31469914

Showing the first eight; more decompositions exist.
