Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31910, here are decompositions:

3 + 31907 = 31910
19 + 31891 = 31910
37 + 31873 = 31910
61 + 31849 = 31910
139 + 31771 = 31910
181 + 31729 = 31910
211 + 31699 = 31910
223 + 31687 = 31910

Showing the first eight; more decompositions exist.
