Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31788, here are decompositions:

17 + 31771 = 31788
19 + 31769 = 31788
37 + 31751 = 31788
47 + 31741 = 31788
59 + 31729 = 31788
61 + 31727 = 31788
67 + 31721 = 31788
89 + 31699 = 31788

Showing the first eight; more decompositions exist.
