Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 984400, here are decompositions:
- 3 + 984397 = 984400
- 17 + 984383 = 984400
- 41 + 984359 = 984400
- 47 + 984353 = 984400
- 59 + 984341 = 984400
- 71 + 984329 = 984400
- 101 + 984299 = 984400
- 233 + 984167 = 984400
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 984,400 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
