Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31908, here are decompositions:

17 + 31891 = 31908
59 + 31849 = 31908
61 + 31847 = 31908
109 + 31799 = 31908
137 + 31771 = 31908
139 + 31769 = 31908
157 + 31751 = 31908
167 + 31741 = 31908

Showing the first eight; more decompositions exist.
