答案

要找出哪两个质数和为241,需要从小于241的所有质数中进行排列组合,直到找到两个质数相加得到241为止。

可以先写出小于241的所有质数:

2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97,101,103,107,109,113,127,131,137,139,149,151,157,163,167,173,179,181,191,193,197,199,211,223,227,229,233,239

接下来,从最小的两个质数开始配对相加,依次向上组合,直到找到两个相加等于241的质数。

2 + 239 = 241

3 + 238 = 241

5 + 236 = 241

7 + 234 = 241

11 + 230 = 241

13 + 228 = 241

17 + 224 = 241

19 + 222 = 241

23 + 218 = 241

29 + 212 = 241

31 + 210 = 241

37 + 204 = 241

41 + 200 = 241

43 + 198 = 241

47 + 194 = 241

53 + 188 = 241

59 + 182 = 241

61 + 180 = 241

67 + 174 = 241

71 + 170 = 241

73 + 168 = 241

79 + 162 = 241

83 + 158 = 241

89 + 152 = 241

97 + 144 = 241

101 + 140 = 241

103 + 138 = 241

107 + 134 = 241

109 + 132 = 241

113 + 128 = 241

127 + 114 = 241

131 + 110 = 241

137 + 104 = 241

139 + 102 = 241

149 + 92 = 241

151 + 90 = 241

157 + 84 = 241

163 + 78 = 241

167 + 74 = 241

173 + 68 = 241

179 + 62 = 241

181 + 60 = 241

191 + 50 = 241

193 + 48 = 241

197 + 44 = 241

199 + 42 = 241

211 + 30 = 241

223 + 18 = 241

227 + 14 = 241

229 + 12 = 241

233 + 8 = 241

因此,相加等于241的质数为2和239。
