Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469476, here are decompositions:

29 + 31469447 = 31469476
53 + 31469423 = 31469476
89 + 31469387 = 31469476
149 + 31469327 = 31469476
173 + 31469303 = 31469476
197 + 31469279 = 31469476
443 + 31469033 = 31469476
449 + 31469027 = 31469476

Showing the first eight; more decompositions exist.
