The number j must be zero or a power of 2. Checked j being powers of two through 2^21. Thus a(5) > 10^2900000. Primes of this magnitude are rare (about 1 in 6.7 million), so chance of finding one is remote with today's computer algorithms and speeds. - Robert Price, Apr 28 2013

Example

j=0: p=1+1=2;
j=1: p=2+59=61;
j=4: p=16+12117361=12117377;
j=32: p=2^32+59^32=464798130469793589516643498190087912509935907401081390977;
the j exponents are powers of 2.
