Maybe with the function STRAFTER https://www.w3.org/TR/sparql11-query/#func-strafter

Example of use:

SELECT ?item ?itemLabel ?itemLabelafter WHERE {
    ?item  wdt:P19 wd:Q647 ; rdfs:label ?itemLabel.
    FILTER (lang(?itemLabel) = "fr").
    BIND ( STRAFTER(?itemLabel, " ") AS ?itemLabelafter )
}
LIMIT 10
