Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31746, here are decompositions:

5 + 31741 = 31746
17 + 31729 = 31746
19 + 31727 = 31746
23 + 31723 = 31746
47 + 31699 = 31746
59 + 31687 = 31746
79 + 31667 = 31746
83 + 31663 = 31746

Showing the first eight; more decompositions exist.
