In that gap you will find:

10982, 14779, 14852, 15331, 15434, 16202, 16303, 16831, 16923, 19875,
21161, 23702, 28127, 29972, 33404, 39315, 41043, 41592, 51211, 59238,
59772, 60612, 66268

Which, if I'm not mistaken, brings that k to 100 primes. Should I insert a dancing banana here?

It appears to roughly have a density of 7 per n doubling, so another 7-10 in the 70000-170000 range is likely.
7 more was comparatively easy:

79481, 87840, 91514, 103375, 104433, 106609, 108981
