Cisco BGP Conversion

I have a good working BGP configuration on our Cisco routers (multiple sites) which each site has two MPLS providers. The config below prefers one carrier over the other and prevents a sitte from becoming a transient site.  I now need to convert the BGP config to our Juniper SRX units. I appreciate any assistance to convert the Cisco config below into a Juniper equivalent.

Thanks again.
