The addition at the end to 1093 of its third digit (from
left), nine, produces 10939, which is prime. The same
thing happens with the greater of the Wieferich primes,
3511. In fact, the addition at the end of one, which is the
third digit of 3511 from left, produces 35111, which is
prime. [Galliani]
