2,1443- is a Cunningham composite of SNFS difficulty 290 from the recent base 2 extension. Hopefully this will be the last one that I have to send to 15e.

2,2174L was done with 33-bit large primes, 2,2174M started with 33-bit but was mostly done with 34-bit. This was the result:
So 2,1091+ should be possible with 34-bit large primes too. Though...
