Primary (ID: 204878) 15531148537834287451848019 (proven prime)
(ID: 204879) 1328978866562629921479826913770763993576029025077236891300535149661607985268076432452768991416777295530777941227 (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.
