Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999984, here are decompositions:
- 5 + 999979 = 999984
- 23 + 999961 = 999984
- 31 + 999953 = 999984
- 53 + 999931 = 999984
- 67 + 999917 = 999984
- 101 + 999883 = 999984
- 131 + 999853 = 999984
- 211 + 999773 = 999984
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 999,984 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
