Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31794, here are decompositions:

23 + 31771 = 31794
43 + 31751 = 31794
53 + 31741 = 31794
67 + 31727 = 31794
71 + 31723 = 31794
73 + 31721 = 31794
107 + 31687 = 31794
127 + 31667 = 31794

Showing the first eight; more decompositions exist.
