Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28934, here are decompositions:

7 + 28927 = 28934
13 + 28921 = 28934
67 + 28867 = 28934
97 + 28837 = 28934
127 + 28807 = 28934
163 + 28771 = 28934
181 + 28753 = 28934
211 + 28723 = 28934

Showing the first eight; more decompositions exist.
