Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102320, here are decompositions:
- 3 + 102317 = 102320
- 19 + 102301 = 102320
- 61 + 102259 = 102320
- 67 + 102253 = 102320
- 79 + 102241 = 102320
- 103 + 102217 = 102320
- 139 + 102181 = 102320
- 181 + 102139 = 102320
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 102,320 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
