Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464, here are decompositions:

67 + 31397 = 31464
71 + 31393 = 31464
73 + 31391 = 31464
107 + 31357 = 31464
127 + 31337 = 31464
131 + 31333 = 31464
137 + 31327 = 31464
157 + 31307 = 31464

Showing the first eight; more decompositions exist.
