Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001328, here are decompositions:
- 5 + 1001323 = 1001328
- 7 + 1001321 = 1001328
- 17 + 1001311 = 1001328
- 37 + 1001291 = 1001328
- 61 + 1001267 = 1001328
- 109 + 1001219 = 1001328
- 131 + 1001197 = 1001328
- 137 + 1001191 = 1001328
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 1,001,328 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
