13917...02101 (1000-digits)

This number is a probable-prime (likely to be a prime but we have not (re-)proven it on this site).

+ Titanic prime obtained by starting with the prime 11 and then inserting the smallest digit (from 0-9) in the leftmost interdigital position that produces a prime. Repeat this until a 1000-digit prime is obtained. [Rivera]
