Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5728, here are decompositions:

11 + 5717 = 5728
17 + 5711 = 5728
59 + 5669 = 5728
71 + 5657 = 5728
89 + 5639 = 5728
137 + 5591 = 5728
197 + 5531 = 5728
227 + 5501 = 5728

Showing the first eight; more decompositions exist.
