1,109,889 & 1,164,501 & 1,172,421

[Math.]  From the most basic 3×3 magic square, where sum of 3 numbers in each row, column and main (left & right) diagonals are all 15:

 8 1 6 3 5 7 4 9 2

.   rows:                8162+3572+4922 = 1,035,369 = 6182+7532+2942

.   columns:           8342+1592+6722 = 1,172,421 = 4382+9512+2762

.   right diagonals:  8522+1742+6392 = 1,164,501 = 2582+4712+9362 and

8522+3962+4172 = 1,056,609 = 2582+6932+7142

.   left diagonals:    6542+8792+1322 = 1,217,781 = 4562+9782+2312 and

6542+7982+2132 = 1,109,889 = 4562+8972+3122.
