Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183400, here are decompositions:
- 3 + 183397 = 183400
- 11 + 183389 = 183400
- 17 + 183383 = 183400
- 23 + 183377 = 183400
- 71 + 183329 = 183400
- 83 + 183317 = 183400
- 101 + 183299 = 183400
- 137 + 183263 = 183400
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 183,400 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
