曾老师您好！
我再验算自己的。

4/997081=1/249280+1/12427617584+1/13081702720

曾老师的最后四个解，我暂时没有多位数的计算器，如果检验就很费劲了，以后再检验吧！

zengyong老师您好！
已经检验了，有两个解是对的:
4/997081=1/249340+1/49722435308+1/907343710
4/997081=1/249288+1/10356680347+1/5288517624

的确错两个，改正如下
4/997081=1/249280+1/13081702720+1/12427617584
4/997081==1/249312+1/1563423008+1/31073032284

所以说，这道难题的好处之一就是：错的就是错的，忽悠不了能人。
