Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31700, here are decompositions:

13 + 31687 = 31700
37 + 31663 = 31700
43 + 31657 = 31700
73 + 31627 = 31700
127 + 31573 = 31700
157 + 31543 = 31700
211 + 31489 = 31700
223 + 31477 = 31700

Showing the first eight; more decompositions exist.
