If we consider only squares,
there's the infinite sequence A064233.
What about cubes etc?
A064233 Numbers which are not the sum of a prime
number and a nonzero square.
1,2,5,10,13,25,31,34,37,58,61,64,85,91,121,127,130,169,196,214,226,289,324,370,379,400,439,526,529,571,625,676,706,730,771,784,829,841,991,1024,1089,1225,1255,1351,1414,1444,1521,1549,1681,1849,1906,1936,2116
