The α-decay chains of 288-287115 are studied along with the possible cluster decay modes by using the preformed cluster model (PCM). The calculated α-decay half-lives are compared with experimental data and other model calculations. The calculated Q-values, penetration probabilities and preformation probabilities factors for α-decay suggest that 283170113, 287172115 and 272165107 parent nuclei are more stable against the α-decay. These alpha-decay chains are further explored for the possibilities of cluster decay. Decay half-lives of different clusters from different nuclei of the decay chains point to the extra stability near or at the deformed shells Z = 108, N = 162 and Z = 100, N = 152. The decay half-lives for 14C and 48Ca clusters are lower than the current experimental limit (≈1028s).
