Notes:
The range 350k ≤ n ≤ 352k for 1005 ≤ k ≤ 1999 (sieved to p = 1.4T) was done for testing the server.

This drive was planned first for the range 1005 ≤ k ≤ 1999 but after P.Benson offered the results from his search
for 1005 ≤ k ≤ 1399 and were checked for completeness, the lower range was set to k = 1401!
