That's really easy:

sub find_closest_primes
{
    my $number = shift;

    my @close_primes;

    for my $close (find_close_numbers( $number ))
    {
         push @close_primes, $close if is_prime( $close );
    }

    return @close_primes;
}

All you have to do is fill in the behavior of find_close_numbers() and is_prime()!
