Explanation:
Most properties of differences of squares seem to be fairly straightforward to prove. I suppose if you did not know the proofs then they would be conjectures. For example:

Any odd number is the difference of squares of two integers.

Any multiple of
#4# is the difference of squares of two integers. 
Any integer of the form
#4k+2# (where#k# is an integer) is not the difference of squares of two integers.
