[10], 31^2=961, (961+1)/2-(159+63+36+19+16+10+8+5+2+1)=162个质数.
第1步,(961+1)/2=481个奇数, 为了计算简捷我们直接将奇数1改成质数2,
第2步,(481-2)/3=159,
第3步,(481-8)/5=94, {94+[(5-1)/2]-2}/3=31, 94-31=63,
第4步,(481-18)/7=66, {66+[(7-1)/2]-2}/3=22,
{66+[(7-1)/2]-8}/5=12, {12+[(5-1)/2]-2}/3=4, (12-4)=8,
66-22-8=36,
第5步,(481-50)/11=39, {39+[(11-1)/2]-2}/3=14, {[(11+1)/2]-2}/3=1, (14-1)=13,
{39+[(11-1)/2]-8}/5=7, {7+[(5-1)/2]-2}/3=2, (7-2)=5,
{39+[(11-1)/2]-18}/7=3, {3+[(7-1)/2]-2}/3=1, (3-1)=2,
39-13-5-2=19,
第6步,(481-72)/13=31, {31+[(13-1)/2]-2}/3=11, {[(13+1)/2]-2}/3=1, (11-1)=10,
{31+[(13-1)/2]-8}/5=5, {5+[(5-1)/2]-2}/3=1, (5-1)=4,
{31+[(13-1)/2]-18}/7=2, {2+[(7-1)/2]-2}/3=1, (2-1)=1,
31-10-4-1=16,
第7步,(481-128)/17=20, {20+[(17-1)/2]-2}/3=8, {[(17+1)/2]-2}/3=2, (8-2)=6,
{20+[(17-1)/2]-8}/5=4, {4+[(5-1)/2]-2}/3=1, (4-1)=3,
{20+[(17-1)/2]-18}/7=1,
20-6-3-1=10,
第8步,(481-162)/19=16, {16+[(19-1)/2]-2}/3=7, {[(19+1)/2]-2}/3=2, (7-2)=5,
{16+[(19-1)/2]-8}/5=3, {3+[(5-1)/2]-2}/3=1, (3-1)=2,
{16+[(19-1)/2]-18}/7=1,
16-5-2-1=8,
第9步,(481-242)/23=10, {10+[(23-1)/2]-2}/3=6, {[(23+1)/2]-2}/3=3, (6-3)=3,
{10+[(23-1)/2]-8}/5=2,
10-3-2=5,
第10步, (481-392)/29=3, {3+[(29-1)/2]-2}/3=5, {[(29+1)/2]-2}/3=4, (5-4)=1,
{3+[(29-1)/2]-8}/5=1, {[(29+1)/2]-8}/5=1, (1-1)=0,
3-1-0=2,
第11步, (481-450)/31=1,
481-159-63-36-19-16-10-8-5-2-1=162. |
