Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28976, here are decompositions:

43 + 28933 = 28976
67 + 28909 = 28976
97 + 28879 = 28976
109 + 28867 = 28976
139 + 28837 = 28976
163 + 28813 = 28976
223 + 28753 = 28976
307 + 28669 = 28976

Showing the first eight; more decompositions exist.
