Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469400, here are decompositions:

13 + 31469387 = 31469400
43 + 31469357 = 31469400
47 + 31469353 = 31469400
73 + 31469327 = 31469400
97 + 31469303 = 31469400
101 + 31469299 = 31469400
107 + 31469293 = 31469400
113 + 31469287 = 31469400

Showing the first eight; more decompositions exist.
