"An Elliptic Curve Primality Proving (ECPP) algorithm was used via a primality proving program, Primo 4.3.0 - LX64, to generate a primality certificate which deterministically verifies the primality of p. The certification process took 39 days and 8 hours to complete using an AMD Ryzen Threadripper 2950X (16-Core, 32-Thread, 3.5GHz Base)."
