Primary (ID: 2171) 130654897808007778425046117 (proven prime)
(ID: 19718) 20432425770035671161623011312767006833529239459264912799347724148565589860873665574742089214931977451028310648821120385824394693361 (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.
