Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469464, here are decompositions:

17 + 31469447 = 31469464
23 + 31469441 = 31469464
41 + 31469423 = 31469464
53 + 31469411 = 31469464
107 + 31469357 = 31469464
137 + 31469327 = 31469464
431 + 31469033 = 31469464
563 + 31468901 = 31469464

Showing the first eight; more decompositions exist.
