Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469794, here are decompositions:

11 + 31469783 = 31469794
53 + 31469741 = 31469794
71 + 31469723 = 31469794
173 + 31469621 = 31469794
233 + 31469561 = 31469794
263 + 31469531 = 31469794
281 + 31469513 = 31469794
347 + 31469447 = 31469794

Showing the first eight; more decompositions exist.
