Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469434, here are decompositions:

11 + 31469423 = 31469434
23 + 31469411 = 31469434
47 + 31469387 = 31469434
107 + 31469327 = 31469434
131 + 31469303 = 31469434
257 + 31469177 = 31469434
401 + 31469033 = 31469434
467 + 31468967 = 31469434

Showing the first eight; more decompositions exist.
