%N Primes of form 2^j + 17^j.
%C The number j must be zero or a power of 2. Checked j being powers of two through 2^20. Thus a(5) > 10^2500000. Primes of this magnitude are rare (about 1 in 5.9 million), so chance of finding one is remote with today's computer algorithms and speeds.  _Robert Price_, Apr 29 2013
%e j=0: p=1+1=2;j=1: p=2+17=19;j=2: p=4+289=293;j=4: p=16+83521=83537; the j exponents are powers of 2.
