Add Or Insert Number (1:50) To Row With No Duplication?

I've a list (Taken from this website; [URL] of 4900 rows with each row have 4 numbers if I want to add or insert one number( from 1 to 50 ) to each row with no duplicate to make it 5 numbers in each row? Is there a formula or Vb code to do this?

Code:
123411256212783129104121135512123161213147121543812162191217471012181911122023

[Code]...

To my calculation Numbers (1:50) have to be use 98 times;(50*98=4900) since each numbers in the list used 392 times(392/ 49 = 8)since there is no duplication when adding numbers (1:50) to rows each numbers must pair with evry other number in that list 8 times.at the moment with out adding the 5th number each number pairs with any other number exactly 24 times but adding process finish it should be 32 (24+8).
