Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31668, here are decompositions:

5 + 31663 = 31668
11 + 31657 = 31668
19 + 31649 = 31668
41 + 31627 = 31668
61 + 31607 = 31668
67 + 31601 = 31668
101 + 31567 = 31668
127 + 31541 = 31668

Showing the first eight; more decompositions exist.
