Create the sample space and weed out the offending options:

11 21 31 41 51 61
12 22 32 42 52 62
13 23 33 43 53 63
14 24 34 44 54 64
15 25 35 45 55 65
16 26 36 46 56 66

Delete everything that doesn't have 2
       
     21
12 22  32 42 52 62
     23
     24
     25
     26
 
Now delete everything that sums to 6 or less

      52 62
25
26
 
and that's it; 4 left out of 36
