%N Primes p such that p + 2^floor(log_2(p)) is prime.
%C a(n) + 2^floor(log_2(a(n))) = A152085(n).
%C If a(n) is written in binary and the leftmost 1 is replaced with "10", then we would have the binary representation of A152085(n), which is a prime.
%C Sequence A091932 contains the related primes p where p - 2^floor(log_2(p)) = prime.
