Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31404, here are decompositions:

7 + 31397 = 31404
11 + 31393 = 31404
13 + 31391 = 31404
17 + 31387 = 31404
47 + 31357 = 31404
67 + 31337 = 31404
71 + 31333 = 31404
83 + 31321 = 31404

Showing the first eight; more decompositions exist.
