Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31712, here are decompositions:

13 + 31699 = 31712
139 + 31573 = 31712
181 + 31531 = 31712
199 + 31513 = 31712
223 + 31489 = 31712
379 + 31333 = 31712
463 + 31249 = 31712
523 + 31189 = 31712

Showing the first eight; more decompositions exist.
