Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100440, here are decompositions:
- 23 + 100417 = 100440
- 29 + 100411 = 100440
- 37 + 100403 = 100440
- 47 + 100393 = 100440
- 61 + 100379 = 100440
- 79 + 100361 = 100440
- 83 + 100357 = 100440
- 97 + 100343 = 100440
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 100,440 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
