Sums & differences

Difference of 2 squares: 528 = 28^{2} - 16^{2} = 37^{2} - 29^{2} = 47^{2} - 41^{2} = 68^{2} - 64^{2} = 133^{2} - 131^{2}

Goldbach conjecture: 528 = 523 + 5 = 521 + 7 = 509 + 19 = 499 + 29 = 491 + 37 = 487 + 41 = 467 + 61 = 461 + 67 = 457 + 71 = 449 + 79 = . . . (only the first 10 pairs are shown)
