COMMENT

10^100+a(135) and 10^100+a(136) are the first twin primes greater than 10^100. - T. D. Noe, Nov 03 2008

For each of the 1000 terms in the table, 10^100 + a(n) was verified by the Magma calculator (http://magma.maths.usyd.edu.au/calc/) as prime. [From Jon E. Schoenfield (jonscho(AT)hiwaay.net), Aug 24 2009]
