There's an urban myth (who knows, it may be true) that the one-time
chairman of Rolls Royce, a company that make aero engines, always flew
the atlantic in 4-engined planes.  When asked why, he replied "because
there are no 5-engined planes."

More seriously, ETOPS regulations include things like upgraded
capability for the suppression of fires in the hold that make them
safer, in that respect, than 3- and 4-engined planes.
