Thats the 45th prime number found having 12,978,189 digits by the Mersenne Prime Search Project.
just 2 weeks later ... the 46th number was found: 237,156,667 -1
BBC has a story on this - Apparently, this was a group computing project - linking computers to carry out the complex calculations...
* Mersenne primes are expressed as two to the power of P, minus one - with P being itself a prime number.
(Thats pretty amazing ...that both the power, and the result has to be a prime)
