收到PrimeGrid的邮件,说找到了一个215789位的素数(3039*2^716821+1)。
提交上Top5000发现排名3198!

Dear Primefinder,


Congratulations! Our records indicate that a computer registered by you has found a unique prime number. This computer is running BOINC, is attached to the PrimeGrid project, and is assigned to the Proth Prime Search. What makes this prime unique is that it's large enough to enter the Top 5000 List in Chris Caldwell's The Largest Known Primes Database.

Since you have auto-reporting selected, the following prime was submitted on your behalf:


Added 102971 : 3039*2^716821+1 (215789 digits)

If you have any questions or concerns, please contact me and we will surely resolve any problem.

Once again, congratulations on your find.  Thank you for participating in PrimeGrid.

John Blazek of PrimeGrid

我找到的5个基本上也就在3000-4000之间。感觉往下找似乎很难的样子。
