Primary (ID: 143239) 252602537987029726871796517081 (proven prime)
(ID: 179308) 5926026885741545983918681524425087770082362359492153948451051185372075590243441 (composite)

Primary factorization keeps track of the smallest (known) prime factor. Secondary factorizations are old results kept when a new smaller prime factor is found, which occasionally happens with ECM.
