Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103820, here are decompositions:
- 7 + 103813 = 103820
- 19 + 103801 = 103820
- 97 + 103723 = 103820
- 139 + 103681 = 103820
- 151 + 103669 = 103820
- 163 + 103657 = 103820
- 229 + 103591 = 103820
- 271 + 103549 = 103820
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 103.820 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
