Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469494, here are decompositions:

47 + 31469447 = 31469494
53 + 31469441 = 31469494
71 + 31469423 = 31469494
83 + 31469411 = 31469494
107 + 31469387 = 31469494
137 + 31469357 = 31469494
167 + 31469327 = 31469494
191 + 31469303 = 31469494

Showing the first eight; more decompositions exist.
