Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130784, here are decompositions:
- 97 + 130687 = 130784
- 103 + 130681 = 130784
- 127 + 130657 = 130784
- 151 + 130633 = 130784
- 163 + 130621 = 130784
- 271 + 130513 = 130784
- 307 + 130477 = 130784
- 337 + 130447 = 130784
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 130,784 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
