Combination without repetition in Mathematica

How could I obtain 48 random pairs of two different elements drawn from Range[96] with no repetition ? That is the 96 elements are only used once.

While I tried Tuples/Subsets combined with Select, I feel there must be a more straightforward way to achieve this.

Please tell me if this is correct:

Partition[RandomSample@Range@96, 2]
