Too bad it wasn't me! I've been running theisprime-finding software on all of my computers for a while. John

On August 23rd, a UCLA computer discovered the 45th known Mersenne prime, 2^43112609-1, a mammoth 12,978,189 digit number! The prime number qualifies for the Electronic Frontier Foundation's $100,000 award for discovery of the first 10 million digit prime number. Congratulations to Edson Smith, who was responsible for installing and maintaining the GIMPS software on the UCLA Mathematics Department's computers.
On September 6th, the 46th known Mersenne prime, 2^37156667-1, a 11,185,272 digit number was found by Hans-Michael Elvenich in Langenfeld near Cologne, Germany! This was the first Mersenne prime to be discovered out of order since Colquitt and Welsh discovered 2110,503-1 in 1988.
The nearly decade long quest for the EFF award came down to a close race to the finish - with just two weeks separating the discovery of the two primes.
As promised, GIMPS will give $50,000 of the EFF award to the UCLA Mathematics Department for discovering the first 10 million digit prime. $25,000 will go to charity, and most of the remainder will go to discoverers of the previous six Mersenne primes.
