Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115130, here are decompositions:
- 3 + 115127 = 115130
- 7 + 115123 = 115130
- 13 + 115117 = 115130
- 31 + 115099 = 115130
- 73 + 115057 = 115130
- 109 + 115021 = 115130
- 157 + 114973 = 115130
- 163 + 114967 = 115130
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 115,130 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
