%N Primes p such that there exists at least one number j and pi(p)= d_1 d_2 ... d_j*d_(j+1) d_(j+2) ... d_k where d_1 d_2 ...d_k is the decimal expansion of p.
%C This sequence is the prime subsequence of the sequence A112012. There is no further term up to prime(26000000).

%e 8883067 is in the sequence because 8883067 is prime;
%e pi(8883067)=595161 & 595161=8883*067. Note that for this term j=4.
