Sieve from 30M to 186M on the rational side (that should get 440M relations).

Test sieving 10k ranges:
Code:
  Q  yield
 34M 34027
 84M 29270
134M 26378
184M 24177
Although if you think a 32/32 job should be on 15e instead of 15e_small I won't mind if you move it there. This is probably near the upper limit for 15e_small.

I'll do the LA.
