Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31994, here are decompositions:

3 + 31991 = 31994
13 + 31981 = 31994
31 + 31963 = 31994
37 + 31957 = 31994
103 + 31891 = 31994
223 + 31771 = 31994
271 + 31723 = 31994
307 + 31687 = 31994

Showing the first eight; more decompositions exist.
