I had a go.

    using System;class A{static void Main(){var a=new System.Collections.BitArray(Convert.FromBase64String("tnOciwgCCAAAAAggAFBxHIkAAAAACICIKABQQBgAAAIgIACAgCAAIqIgigCCADfWuIgAAAACAIAAAAAwCICAIAAAYRkAAAAAAggAgAAIIoAACA=="));int c, d;for(var i=0;i<652;i++){if(a[i]){c=Math.DivRem(i,26,out d);Console.Write("{0}{1} ",(char)('A' + c),(char)('@' + d));}}}}

Ungolfed:

    using System;

    class A
    {
    	static void Main()
    	{
    		var a = new System.Collections.BitArray(Convert.FromBase64String(
                "tnOciwgCCAAAAAggAFBxHIkAAAAACICIKABQQBgAAAIgIACAgCAAIqIgigCCADfWuIgAAAACAI" + 
                "AAAAAwCICAIAAAYRkAAAAAAggAgAAIIoAACA=="));
    		int c, d; 
    		for(var i = 0; i < 652; i++)
    		{
    			if(a[i])
    			{
    				c = Math.DivRem(i, 26, out d);
    				Console.Write("{0}{1} ", (char)('A' + c), (char)('@' + d));
    			}
    		}
    	}
    }
