Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26908, here are decompositions:

5 + 26903 = 26908
17 + 26891 = 26908
29 + 26879 = 26908
47 + 26861 = 26908
59 + 26849 = 26908
107 + 26801 = 26908
131 + 26777 = 26908
149 + 26759 = 26908

Showing the first eight; more decompositions exist.
