Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118020, here are decompositions:
- 29 + 117991 = 118020
- 31 + 117989 = 118020
- 41 + 117979 = 118020
- 43 + 117977 = 118020
- 47 + 117973 = 118020
- 61 + 117959 = 118020
- 83 + 117937 = 118020
- 103 + 117917 = 118020
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 118,020 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
