Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31704, here are decompositions:

5 + 31699 = 31704
17 + 31687 = 31704
37 + 31667 = 31704
41 + 31663 = 31704
47 + 31657 = 31704
61 + 31643 = 31704
97 + 31607 = 31704
103 + 31601 = 31704

Showing the first eight; more decompositions exist.
