Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484, here are decompositions:

3 + 31481 = 31484
7 + 31477 = 31484
97 + 31387 = 31484
127 + 31357 = 31484
151 + 31333 = 31484
157 + 31327 = 31484
163 + 31321 = 31484
307 + 31177 = 31484

Showing the first eight; more decompositions exist.
