Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2916, here are decompositions:

7 + 2909 = 2916
13 + 2903 = 2916
19 + 2897 = 2916
29 + 2887 = 2916
37 + 2879 = 2916
59 + 2857 = 2916
73 + 2843 = 2916
79 + 2837 = 2916

Showing the first eight; more decompositions exist.
