On 24 February 2016, 20:53:55 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

43163894^131072+1

The prime is 1,000,751 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 16th for Generalized Fermat primes and 154th overall.

The discovery was made by David E. Miller (dem0707) of the United States using an NVIDIA GeForce GTX 980 in an Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz with 16GB RAM, running Windows 7 Professional. This GPU took about 26 minutes to probable prime (PRP) test with GeneferOCL2. David is a member of the Crunching@EVGA team.

The prime was verified on 24 February 2016, 21:37:52 UTC by Alen Kecic (Freezing) of Germany using an NVIDIA GeForce GTX 660 Ti in an Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz with 8GB RAM, running Windows 7 Professional. This GPU took 48 minutes to probable prime (PRP) test with GeneferOCL2. Alen is a member of the SETI.Germany team.

For more details, please see the official announcement.
