Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31718, here are decompositions:

19 + 31699 = 31718
31 + 31687 = 31718
61 + 31657 = 31718
151 + 31567 = 31718
229 + 31489 = 31718
241 + 31477 = 31718
331 + 31387 = 31718
397 + 31321 = 31718

Showing the first eight; more decompositions exist.
