Create 'n' number random pairwise combination of words
File 1 contains the list of words that needed to be randomly paired:

Code:
Tiger
Cat 
Fish
Frog
Dog
Mouse
Elephant
Monkey

File 2 contains the pairs that should not be used (in any solution) during random pairing.

Code:
Elephant-Dog
Cat-Fish
Monkey-Frog

Dog-Elephant, Fish-Cat, Frog-Monkey should also be deleted as their pair appeared in File2 (irrespective to direction)
I need total 6 solutions and in every solution, there should be maximum of 5 pairs.
Tiger-Cat and Cat-Tiger should be treated as same and if they appear together in any solution one should be deleted.
Same pair such as Frog-Dog can be appear in many solutions.

The output looks like (here one one solution is given).

Code:
Tiger-Cat
Cat-Dog
Monkey-Cat
Frog-Dog
Elephant-Cat
