Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28964, here are decompositions:

3 + 28961 = 28964
31 + 28933 = 28964
37 + 28927 = 28964
43 + 28921 = 28964
97 + 28867 = 28964
127 + 28837 = 28964
151 + 28813 = 28964
157 + 28807 = 28964

Showing the first eight; more decompositions exist.
