Examples
In order of the size of the prime, not the initial cube, so that the sequence is strictly increasing: 2^3 - 1 = 7 4^3 - 11 = 53 8^3 - 111 = 401 12^3 - 1111 = 617 24^3 - 11111 = 2713 18^3 - 1111 = 4721 62^3 - 111111 = 127217 68^3 - 111111 = 203321 92^3 - 111111 = 667577 132^3 - 1111111 = 1188857 168^3 - 1111111 = 3630521 2232^3 - 11111111111 = 8320057 282^3 - 11111111 = 11314657 288^3 - 11111111 = 12776761 294^3 - 11111111 = 14301073 328^3 - 11111111 = 24176441 364^3 - 11111111 = 37117433 394^3 - 11111111 = 50051873 408^3 - 11111111 = 56806201 1058^3 - 1111111111 = 73176001 454^3 - 11111111 = 82465553
