Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001666, here are decompositions:
- 7 + 1001659 = 1001666
- 37 + 1001629 = 1001666
- 73 + 1001593 = 1001666
- 79 + 1001587 = 1001666
- 97 + 1001569 = 1001666
- 103 + 1001563 = 1001666
- 139 + 1001527 = 1001666
- 199 + 1001467 = 1001666
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 1,001,666 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
