primes in pi: 1, 2, 6, 38, 16208, 47577, 78073, ...

No, no, no.  Of course you want to look in base e.  For any initial 
sequence, there is only one integer which has that as the part before 
the "decimal" point in base e: just take the ceiling.  So, for example, 
101 = e^2+1 = 8.389... represents the number 9.

I am somewhat serious about pi base e.  So far as I can see, pi base e 
= 10.101002020002111120020101120... as per A050948Pi expressed in base 
1/e: Pi = Sum a(i)*exp(-i), i=-1,0,1,...
 
Now, in what base should we examine substrings of this for primality?  
In the unnatural base 10, ...
