Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001784, here are decompositions:
- 41 + 1001743 = 1001784
- 61 + 1001723 = 1001784
- 71 + 1001713 = 1001784
- 97 + 1001687 = 1001784
- 101 + 1001683 = 1001784
- 163 + 1001621 = 1001784
- 191 + 1001593 = 1001784
- 197 + 1001587 = 1001784
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,001,784 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
