Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31694, here are decompositions:

7 + 31687 = 31694
31 + 31663 = 31694
37 + 31657 = 31694
67 + 31627 = 31694
127 + 31567 = 31694
151 + 31543 = 31694
163 + 31531 = 31694
181 + 31513 = 31694

Showing the first eight; more decompositions exist.
