      Description

      From the example in ARROW-5430:

      In [16]: pa.array([14989096668145380166, 15869664087396458664], type=pa.uint64())                                                                                                                                   
      Out[16]: 
      <pyarrow.lib.UInt64Array object at 0x7ff7c51bdf48>
      [
        -3457647405564171450,
        -2577079986313092952
      ]
      

      I think the actual conversion is correct, and it's only the printer that is going wrong, as to_numpy gives the correct values:

      In [17]: pa.array([14989096668145380166, 15869664087396458664], type=pa.uint64()).to_numpy()                                                                                                                        
      Out[17]: array([14989096668145380166, 15869664087396458664], dtype=uint64)
