Primary (ID: 132229) 847586878961383719143557147 (proven prime)
(ID: 167793) 19437798171947544710577544053773727001897574513510194035917246067778035440161293571 (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.
