Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100400, here are decompositions:
- 7 + 100393 = 100400
- 37 + 100363 = 100400
- 43 + 100357 = 100400
- 67 + 100333 = 100400
- 103 + 100297 = 100400
- 109 + 100291 = 100400
- 163 + 100237 = 100400
- 193 + 100207 = 100400
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 100,400 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
