前 66位质数的和是多少?

前66位质数分别是1~100
2.3.5.7.11.13.17.19.23.29.31.37.41.43.47.53.59.61.67.71. 73.79.83.89.97
共25个,和为1060

101~200
101.103.107.109.113.131.137.139.147.149.151.157.163.167.173.179.181.191.193.197.199
共21个,和为3187

201~300
211.223.227.229.233.239.241.251.257.263.269.271.277.281.283.293
共16个,和为4048

301~400
307.311.313.317.331.337.347.349.353.359.367.373.379.383.389.397
共16个,因为只需计算前66个质数的和,所以只需算301~400 的前四位,和为1248

故前66位质数的和为1060+3187+4048+1248=9543

不好算……

9543！
