Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000800, here are decompositions:
- 7 + 1000793 = 1000800
- 23 + 1000777 = 1000800
- 37 + 1000763 = 1000800
- 79 + 1000721 = 1000800
- 103 + 1000697 = 1000800
- 109 + 1000691 = 1000800
- 131 + 1000669 = 1000800
- 149 + 1000651 = 1000800
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 1,000,800 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
