Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31392, here are decompositions:

5 + 31387 = 31392
13 + 31379 = 31392
59 + 31333 = 31392
71 + 31321 = 31392
73 + 31319 = 31392
139 + 31253 = 31392
173 + 31219 = 31392
199 + 31193 = 31392

Showing the first eight; more decompositions exist.
