This is the semiprime analog of A114923.
There are only two such semiprimes < 10^4 with more than one solution: 2095 and 9897.
EXAMPLE
206^3 = 35^3 + 77^3 + 202^3.
519^3 = 4^3 + 303^3 + 482^3
703^3 = 111^3 + 291^3 + 685^3.
869^3 = 466^3 + 629^3 + 674^3.
2095^3 = 339^3 + 753^3 + 2059^3 = 543^3 + 1119^3 + 1969^3 (two ways).
9897^3 = 537^3 + 1454^3 + 9886^3 = 2071^3 + 3183^3 + 9755^3 (two ways).
Each of these numbers (other than the exponent 3) is a semiprime (A001358).
