The Prime Gap List Project catalogs the first known occurrence of each prime gap size. Many even gap sizes have never been observed — discovering one is an automatic first-occurrence record.
This page shows gap sizes in a configurable range that are not yet in the global database. If your miner discovers any of these gap sizes, it will be a genuine mathematical first.
All even gaps below 122,290 are already known. Missing gaps start there.
