I've tried many random numbers and even original value acquired by:

# ceph daemon osd.0 config get osd_memory_target
{
    "osd_memory_target": "4294967296"
}

# ceph versions
{
    "mon": {
        "ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9)
nautilus (stable)": 4
    },
    "mgr": {
        "ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9)
nautilus (stable)": 4
    },
    "osd": {
        "ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9)
nautilus (stable)": 24
    },
    "mds": {},
    "overall": {
        "ceph version 14.2.6 (f0aa067ac7a02ee46ea48aa26c6e298b5ea272e9)
nautilus (stable)": 32
    }
}


BTW I've opened offical bug: https://tracker.ceph.com/issues/43766
