Models with >99,999 atoms, or >62 chains, do not fit in the PDB format (see [[Jmol/Visualizing large molecules]]). Such models are available only in mmCIF format, and not in the PDB format. However, in 2024, such models are available in subsets in PDB format. For example, at [https://www.rcsb.org/structure/5LEG 5LEG], look for "PDB format-like files" in the ''Download Files'' menu.
