• It was a genuine mistake. I posted the post very late at night, and I was tired. The correct version is: 1=1 1+1=2 2=2 1+1+1=3 1+2=3 3=3 1+1+1+1=4 1+1+2=4

It was a genuine mistake. I posted the post very late at night, and I was
tired. The correct version is:

1=1

1+1=2
2=2

1+1+1=3
1+2=3
3=3

1+1+1+1=4
1+1+2=4
1+3=4
2+2=4
4=4

--- and for primes ---

2=2

3=3

2+2=4

2+3=5
5=5

2+2+2=6
3+3=6

2+2+3=7
2+5=7
7=7

The first problem I solved about 5 years ago, I can't fully remember how,
but it reduces to a fairly simple formula, and you can even determine the
number of sums to n with k terms.

That was my whole point, Jud. He was the one who missed it off the
first list, but included it in the second list.
