Collecting numbers for particular sums-2

 This is  a rejoinder to my earlier blog with same title.
There has been no response although it is a simple problem of logic
For exnmple instead of collecting 6 numbers from group A,you can consider removing 2 numbers from that group. Same logic with group B
Following are the solutions
Group A-total 220- by removing 55 and 11....group B-total 110- by removing 38 and 49
Group A-total 228-by removing 17 and 41....group B-total 114-by removing  45 and 38
Group A-total 234-by removing 11 and 41....group B-total 117-by removing  31 and 49
Is it not simple?

You will find the square of 1490712 is 2222222266944
Also the square of 1490713 is 2222225248369
