Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115320, here are decompositions:
- 11 + 115309 = 115320
- 17 + 115303 = 115320
- 19 + 115301 = 115320
- 41 + 115279 = 115320
- 61 + 115259 = 115320
- 71 + 115249 = 115320
- 83 + 115237 = 115320
- 97 + 115223 = 115320
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 115,320 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
