Someday, we might get this approximately right.

 50 =  2^7 - -1^3
 82 =  9^2 - -1^3
226 = 15^2 - -1^3
246 = 11^2 - -5^3
290 = 17^2 - -1^3
342 =  7^3 -  1^3  (Thanks, Reinhart)
442 = 21^2 - -1^3

So here's the latest version of the sequence.

6 14 34 42 58 62 66 70 78 86 90 102 110 114 130 158 178 182
202 210 230 238 254 258 266 274 278 302 306 310 314 322 326

150 =  5^2 - -5^3
170 = 13^2 - -1^3 = 59^3 - 453^2
206 =  9^2 - -5^3
