Narrative:
We were ferrying [an] aircraft. We knew that this aircraft had previous issues with pressurization on other recent occasions. On climbout everything looked normal. Rate of climb was approximately 200 [and the] cabin differential looked normal. After crossing FL300; we received a cabin altitude warning and EICAS message. We performed the memory items and asked for a descent to FL250 where the cabin was still at 15;000 so we continued the descent to FL230 where the cabin started to come back to 10;000 and stabilize.after the QRH was completed we wrote numerous messages to [the] company asking for new fuel burn numbers at the lower altitude. We had a mechanic on board [and] we asked him his opinion on everything or if he had a different way to look at things. He agreed with our assessments. While waiting; we checked the oxygen tables to make sure we had enough oxygen for our plan; in which we did. We had planned to wait to hear from [the] company before making a decision. We then changed the step climb in the FMC in case the new numbers were okay to continue and we would not be able to step climb anymore; to which we received a message of insufficient fuel and showed us landing with 10.2 in ZZZ. At that time; we asked to return to ZZZZ and requested priority handling. We then made it back to ZZZZ with no further issues.
