Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118820, here are decompositions:
- 19 + 118801 = 118820
- 73 + 118747 = 118820
- 103 + 118717 = 118820
- 139 + 118681 = 118820
- 151 + 118669 = 118820
- 199 + 118621 = 118820
- 271 + 118549 = 118820
- 277 + 118543 = 118820
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 118,820 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
