The prime indices n are 1, 11, 156, 158, 160, 168, 170, 587, 589, 1026,... and the cubes are 0, 27, 343 (repeated 5 times), 1331 (repeated 2 times), 2197, 3375, 4913 (repeated 2 times),... - R. J. Mathar, Jul 27 2013

EXAMPLE
31 is in the sequence because 31 = prime(11) and prime(3*11) - prime(2*11) - prime(11) = 137 - 79 - 31 = 27 = 3^3.
