Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002668, here are decompositions:
- 151 + 1002517 = 1002668
- 157 + 1002511 = 1002668
- 181 + 1002487 = 1002668
- 211 + 1002457 = 1002668
- 241 + 1002427 = 1002668
- 307 + 1002361 = 1002668
- 379 + 1002289 = 1002668
- 409 + 1002259 = 1002668
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 1,002,668 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
