Default LL test speed up?

I'm just curious if anyone has thought about backtracking from the end of a LL, and then going back to S(1) = 4, if S(1) != 4 from this backtrack, then we know that if the number is not prime. Possibly breaking a number into two parts, and then seeing if the two LL numbers are equal or not. etc...
