Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999804, here are decompositions:
- 31 + 999773 = 999804
- 41 + 999763 = 999804
- 83 + 999721 = 999804
- 137 + 999667 = 999804
- 151 + 999653 = 999804
- 173 + 999631 = 999804
- 181 + 999623 = 999804
- 191 + 999613 = 999804
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 999,804 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
