How run only half of tests

I have a question about pom.xml.

I have 1000 TC and want to run only part of them, about 500. How can I do that in my pom.xml file?

<configuration>
    <skipTests>${skip.selenium.tests}</skipTests>
    <rerunFailingTestsCount>2</rerunFailingTestsCount>
    <parallel>classesAndMethods</parallel>
    <threadCount>24</threadCount>
    <systemProperties>
        <property>
            <name>webdriver.base.url</name>
            <value>${webdriver.base.url}</value>
        </property>
    </systemProperties>
    <includes>
        <include>**/*IT.java</include>
    </includes>
</configuration>
