Ok, but then why not 1 and 2, they are also both prime. Of course I see
the use of taking some bigger number, but still the question remains:
why some primes around 1200? Because accidentally the implementor knew
them, then?
Consider what happens when you create a composite hashCode either by
multiplication, addition, xor, shift/or etc .
My guess is those numbers help the boolean effect from getting lost.
