Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118900, here are decompositions:
- 3 + 118897 = 118900
- 101 + 118799 = 118900
- 113 + 118787 = 118900
- 149 + 118751 = 118900
- 191 + 118709 = 118900
- 227 + 118673 = 118900
- 239 + 118661 = 118900
- 281 + 118619 = 118900
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 118,900 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
