Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115560, here are decompositions:
- 7 + 115553 = 115560
- 13 + 115547 = 115560
- 37 + 115523 = 115560
- 47 + 115513 = 115560
- 61 + 115499 = 115560
- 89 + 115471 = 115560
- 101 + 115459 = 115560
- 131 + 115429 = 115560
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 115,560 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
