The prime is 1,021,515 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 203rd overall.

The discovery was made by Douglas B. McKay (KD7LRJ) of the United States using an Intel(R) Core(TM) i7-4790K CPU @ 4.00 GHz with 32GB RAM, running Microsoft Windows 10 Professional Edition. This computer took about 1 hour 15 minutes to complete the primality test using LLR. Douglas is a member of the Aggie The Pew team.

The prime was verified on 3 May 2017 20:11:14 UTC, by John Murphy (TheDawgz) of the United States using an Intel Virtual CPU with 1GB RAM, running Linux. This computer took about 1 hour 24 minutes to complete the primality test using LLR. John is a member of the Aggie The Pew team.
