8 = 4 + 4 (Posted on 2004-08-26)

In the line of

1233 = 12² + 33²

990100 = 990² + 100²

can you find an eight digit number with the same property? Even longer numbers?

By exaustive search the only only 4, 6, and 8 digits numbers are

12, 33

88, 33

990, 100

9412, 2353

I would have searched 10 digit numbers, except exceeds the size of a 32 bit integer, and I'm too lazy to program multi-word arithmetic. clutes
