Consider this equation

Where P1, P2 are Primes numbers greater than 2, n is an integer and Ps is the resulting Prime

My computer Intel core I5 seems won't be able to calculate the prime beyond n>50 when P1 & P2 not even larger than 20.

Taking log on one prime yields:

2^nlogP1, when n=20, and P>10, the prime calculated could be at least 1 million digits.

Some primes are governed by this generalize equation and can be read here www.oeis.org.
