Glossary: Prime Pages: Top 5000: 
In the same way that the term titanic prime was coined
for 1,000+ digit primes and gigantic prime for 10,000+
digit primes; we define a megaprime to be a prime
with at least 1,000,000 digits.
Almost all primes are megaprimes (because almost all integers have more than one million digits), but, as of March 2008, only fourteen are known!
