Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5128, here are decompositions:

29 + 5099 = 5128
41 + 5087 = 5128
47 + 5081 = 5128
89 + 5039 = 5128
107 + 5021 = 5128
191 + 4937 = 5128
197 + 4931 = 5128
239 + 4889 = 5128

Showing the first eight; more decompositions exist.
