My solution assumed that no integers were duplicated, and since adding up 2->63 equals EXACTLY 2015, it was likely that it was the intended solution.
The prompt does not specifically state either way, so it is up for interpretation.
Good catch !
But it might also be a coincidence, since many exercices simply use the current year when a random "large" integer is required.
If no 2 same integers can be chosen in the decomposition of N, then you're right.
