I am not sure if you are aware or not - your sequence is a recursive quadratic polynomial. You can just specify the seed and the depth level.

x_next=f(x) where f(x)=x^2-x+1

2-->3-->7-->43-->

For sieve:-
Factors would be of format factor==1 (mod 6)
Also given the recurrent nature you can easily calculate which depth level a prime p will divide.
