EXAMPLE

199 is on the list because it can be written in two (prime) ways as the sum of either three (prime) or five (prime) consecutive primes: 61+67+71 = 31+37+41+43+47.

311 is not on the list because it can be written as the sum of three, five, seven, or eleven consecutive primes: four (not prime) ways. - Hans Havermann, Mar 24 2018
