For some reason I thought that 8am would be a good time to book for New Year's eve. Now I'm not quite sure why I chose the earliest appointment!

The difference of two squares is very useful!
n²-1=(n-1)(n+1)
If n²-1 is prime, then n-1=1, or n+1=1.
The only valid solution is when n=2 you might be looking for a very long time in your search for another one!
