Prime lists and Computation

Q1. Given a large integer {x} . If it is proved to be prime, what other
information is generated?

1. Complete Prime list to x^(1/2)?
2. The modulo residues?


Q2 Is their a complete list of primes to X Published?
X~ 10^20? X~10^30. X= 10^??
,

Q3 Storage: When does it become more efficient to store the prime list than
to generate/calculate it.

Q4 What would be the expected time to factor a 1 MB file, if it was
interpreted as a very integer.
