Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469310, here are decompositions:

7 + 31469303 = 31469310
11 + 31469299 = 31469310
17 + 31469293 = 31469310
23 + 31469287 = 31469310
31 + 31469279 = 31469310
71 + 31469239 = 31469310
101 + 31469209 = 31469310
113 + 31469197 = 31469310

Showing the first eight; more decompositions exist.
