Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108800, here are decompositions:
- 7 + 108793 = 108800
- 31 + 108769 = 108800
- 61 + 108739 = 108800
- 73 + 108727 = 108800
- 151 + 108649 = 108800
- 157 + 108643 = 108800
- 163 + 108637 = 108800
- 229 + 108571 = 108800
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 108,800 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
