New files in the 270280k range sieved to 2150bn are now available.
BTW, here is the number of candidates per k in the 270280k range sorted in their decresing order together with the number of primes found so far. Code:
k #cand #primes 870667875 1461 4 1952775825 1455 3 804003525 1415 3 460735275 1408 3 3467560635 1403 0 918332415 1367 4 697942245 1310 2 2022381375 1303 5 1738812075 1291 1 1626176475 1285 2 779602395 1283 0 1694614845 1278 3 663301485 1271 1 3276742755 1250 3 1325978745 1241 3 67342275 1211 1 Observations: 1) k=3467560635 has a lot of candidates surviving sieving yet it is together with k=779602395 without primes. 2) k=2022381375 is in the middle by number of candidates but it produced the largest number of primes (5). 3) k=870667875 on the top produced many primes as expected (4). 4) k=3276742755 and k=1325978745 are near the bottom but with 3 primes each they are the most prolific.
