Primary (ID: 54830) 2519545342349331183143 (proven prime)
(ID: 55066) 64221033302610602731205118202619944690689404830256256584941596225721838231807265844746626948473 (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.
