Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2908, here are decompositions:

5 + 2903 = 2908
11 + 2897 = 2908
29 + 2879 = 2908
47 + 2861 = 2908
71 + 2837 = 2908
89 + 2819 = 2908
107 + 2801 = 2908
131 + 2777 = 2908

Showing the first eight; more decompositions exist.
