Primary (ID: 86) 217533000184835774779 (proven prime)
(ID: 1710) 2545693149432097517236215774920944033452103655836015380618128961471066629285544401 (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.
