Requiring a(n+1) > a(n) leads to the finite sequence A073860. Not allowing repetition leads to A073698. - M. F. Hasler, Apr 07 2009
EXAMPLE
2+2 = 4 = 2^2, 2+2+23 = 27 = 3^3.
PROG
(PARI) s=0; for( n=1, 999, t=floor(sqrtn(s, n)); until( isprime( t++^n-s), ); print1( t^n-s, ", "); s=t^n) \\ M. F. Hasler, Apr 07 2009
