Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2910, here are decompositions:

7 + 2903 = 2910
13 + 2897 = 2910
23 + 2887 = 2910
31 + 2879 = 2910
53 + 2857 = 2910
59 + 2851 = 2910
67 + 2843 = 2910
73 + 2837 = 2910

Showing the first eight; more decompositions exist.
