Closest prime below 9587 is 9551, with a big gap of 36.
All 36 random integers (9552 to 9587) will go for 9587.

With prime table, removing prime gap bias is trivial: pick a random index, then lookup the prime.

To be honest, I have no idea what you want to say here – ?!?
How is this related to this thread's subject?

I think Klemm prime-wheel code do this ...

Sure, this also is the idea behind Gamo's original program. Generate an odd random integer (here within the wrong range, though) and check if it's prime. If not, try another one.
