Primary (ID: 149225) 258694036490465188007661621181 (proven prime)
(ID: 182779) 61290976632246205159859797883745324359410005320218812300686402057921950794861660261614062424515380848359324664206716851 (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.
