On 4 October 2014, 22:32:24 UTC, PrimeGrid’s The Riesel Problem project eliminated k=502573 by finding the mega prime:

502573*2^7181987-1

The prime is 2,162,000 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 20th overall. This is the largest prime found in The Riesel Problem and PrimeGrid's 14th elimination. 50 k's now remain.

The discovery was made by Denis Iakovlev (Goliaf-RS) of Russia using an Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz with 8 GB RAM running Windows 7 Professional. This computer took about 19 hours and 40 minutes to complete the primality test using LLR. Denis is a member of the Russia Team.

The prime was verified on 5 October 2014, 11:48:03 UTC, by Russell Mathers (Russ) of the United Kingdom using an Intel(R) Core(TM) i7-3960X CPU @ 3.30GHz with 16 GB RAM running Microsoft Windows 7 Professional. This computer took about 18 hours and 46 minutes to complete the primality test using LLR.
