Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001288, here are decompositions:
- 97 + 1001191 = 1001288
- 181 + 1001107 = 1001288
- 199 + 1001089 = 1001288
- 271 + 1001017 = 1001288
- 307 + 1000981 = 1001288
- 367 + 1000921 = 1001288
- 439 + 1000849 = 1001288
- 619 + 1000669 = 1001288
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 1,001,288 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
