On 14 September 2016 04:24:46 UTC, PrimeGrid’s Sophie Germain Prime Search found World Record twin primes:

2996863034895*2^1290000±1

The twin primes are 388,342 digits long, eclipsing the previous record of 200,700 digits. They will enter Chris Caldwell's The Largest Known Primes Database ranked 1st for twins, and each entered individually ranked 4180th overall.

The discovery was made by Tom Greer (tng*) of the United States using an Intel(R) Xeon(R) CPU E5-2623 v3 @ 3GHz with 32 GB RAM running Windows 10 Professional. This computer, using LLR, took approximately 23 minutes to complete the primality tests of both primes. Tom is a member of the Sicituradastra. team.

The prime was verified on 15 September 2016 01:32:51 UTC, by Don Palmer (Don Palmer) of Canada using an Intel(R) Core(TM)2 Duo CPU E7600 @ 3.06GHz with 4 GB RAM running OS X 10.11.6.
