Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12908, here are decompositions:

19 + 12889 = 12908
67 + 12841 = 12908
79 + 12829 = 12908
109 + 12799 = 12908
127 + 12781 = 12908
151 + 12757 = 12908
211 + 12697 = 12908
271 + 12637 = 12908

Showing the first eight; more decompositions exist.
