Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2928, here are decompositions:

11 + 2917 = 2928
19 + 2909 = 2928
31 + 2897 = 2928
41 + 2887 = 2928
67 + 2861 = 2928
71 + 2857 = 2928
109 + 2819 = 2928
127 + 2801 = 2928

Showing the first eight; more decompositions exist.
