Sieve on 15e_small from 40M to 140M on the algebraic side (this may be a bit too much but I'm still getting to know 15e).

Test sieving 10k ranges:
Code:
  Q  yield
 40M 29466
 80M 27130
120M 23736
160M 18309
200M 18935

I queued this job as f45_151m1, though I hedged a bit on the sieving range and went with 40-130M. Can add more Q if needed but sieving on the algebraic side can be noisy - sometimes the yield exceeds estimates.
