Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31790, here are decompositions:

19 + 31771 = 31790
61 + 31729 = 31790
67 + 31723 = 31790
103 + 31687 = 31790
127 + 31663 = 31790
163 + 31627 = 31790
223 + 31567 = 31790
277 + 31513 = 31790

Showing the first eight; more decompositions exist.
