Look at it this way; consider the value of: $(2^{1019} - N * 2^{34} / 3)^3$ Using the binomial expansion, we see that it equal to: $(2^{1019})^3 - 3 * (2^{1019})^2 * N * 2^{34}/3 + 3 * 2^{1019} * (N * 2^{34} / 3)^2 - (N * 2^{34} / 3)^3$ or (simplifying): $2^{3057} - N * 2^{2072} + G$ where $G = N^2/3 * 2^{1087} - N^3/27 * 2^{102} < 2^{2072}$ for the ...
