On 18 March 2017, 21:52:24 UTC, PrimeGrid’s Generalized Fermat Prime Search found the Generalized Fermat mega prime:

45570624^131072+1

The prime is 1,003,840 digits long and enters Chris Caldwell's The Largest Known Primes Database ranked 22nd for Generalized Fermat primes and 231st overall.

The discovery was made by Vince Splain (yank) of The United States using an NVIDIA GeForce GTX 980 in an Intel(R) Core(TM) i7-5960X CPU at 3.00GHz with 16GB RAM, running Microsoft Windows 7 Professional Edition. This GPU took about 14 minutes to probable prime (PRP) test with GeneferOCL4. Vince is a member of the US Navy team.

The prime was verified on 20 March 2017, 03:07:07 UTC by Brett Melvold (AgentQ) of Australia using an AMD R9 Fury Series GPU in an Intel(R) Core(TM) i7-5820K CPU at 3.30GHz with 32GB RAM, running Microsoft Windows 10 Professional Edition. This GPU took about 25 minutes to probable prime (PRP) test with GeneferOCL4. Brett is a member of the BOINC@AUSTRALIA team.

The PRP was confirmed prime by an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 16GB RAM, running Microsoft Windows 10 Professional. This computer took about 2 hours 38 minutes to complete the primality test using LLR.
