Since you need at least two numbers to create a sum, I'm going to say "no."
Wrong
Take any value, x as the first number and then take 658-x as the second. So, if x = 2 the other number is 658-2= 656 or, of x - 20 then the other is 658-20 = 638 or if x = 21.5 then the other is 658-21.5 = 636.5
658.
173, 175, 177
There are infinte amount of answers to that question, like: 640 + 18 = 658 201 + 457 = 658 303.5 + 354.5 = 658
There are 3 whose sum is 45 whose sum is 57 whose sum is 69 whose sum is 711 whose sum is 813 whose sum is 915 whose sum is 1017 whose sum is 1119 whose sum is 1219 whose sum is 1317 whose sum is 1415 whose sum is 1513 whose sum is 1611 whose sum is 179 whose sum is 187 whose sum is 195 whose sum is 203 whose sum is 211 whose sum is 22.
The sum of a single number is itself. So the only number whose sum equals 2 is 2.
There are no 5 odd numbers whose sum is 50. (The sum of 5 odd numbers is an odd number whereas 50 is an even number.)
653 and 5
No.
The number is 6.
