Title: Table for 2? An "edge" case extension of the Oberwolfach problem

Abstract: Originally posed by Ringel in 1967, the Oberwolfach problem asks for which 2-regular graphs G can the complete graph K_n be decomposed into edge-disjoint copies of G.  Formulated another way, the task becomes to seat n individuals around round tables each day such that after the last day, each person has sat next to each other exactly once.  We extend the Oberwolfach problem to consider tables of size 2, that is we aim to decompose K_n into factors consisting of the union of 2-regular graphs along with some number of edges
