A router can forward a broadcast between subnets, but only if configured to do so. By default, a router will not forward a broadcast (nor would you want it to forward all broadcasts, one of the key purposes of a router is to break up layer 3 broadcast domains).
Probably the most common usage of forwarding a broadcast on a router is DHCP, where you can forward DHCP requests to a central DHCP server(s), instead of having a DHCP server on each subnet.
Is there a purposes or context that you need a list of broadcasts for?
