Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999906, here are decompositions:
- 23 + 999883 = 999906
- 43 + 999863 = 999906
- 53 + 999853 = 999906
- 97 + 999809 = 999906
- 137 + 999769 = 999906
- 157 + 999749 = 999906
- 179 + 999727 = 999906
- 223 + 999683 = 999906
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 999,906 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
