Looks like my above formula is good, my reasoning:
we have q=(1-e)^B probability that in a single block all B iterations is good. You have 2*sqrt(B) iterations to do the in the check per block,

Destroyed?
rate=0.1;year=21;(1+rate)^year
rate=0.03;year=3;(1-(1+rate)^(-year))/rate
answer:
%1 = 7.4002499442581601012110000000000000000
%2 = 2.8286113548946809221333416306177114687

Very standard heuristic idea gives that we are expecting very few [maybe zero] composites for G=nextprime(n!)-n! [if we exclude the G<2 cases].
As you noted to find composite G we need G>n^2 so...
