what are the three ways to obtain 7 by summing primes?! 2+5, 2+2+3, and?
Found at a blog that if a number is prime, wrongly some people consider this a sum. So the third way to obtain 7 would be 7 by itself, which is wrong, because it should actually be 7+0, but 0 is not a prime (and 7 by itself is not a sum). https://email@example.com/counting-the-ways-to-express-a-number-as-a-sum-of-primes-e5e871b48193#:~:text=For%20the%20number%207%20we,as%20a%20sum%20of%20primes.
