Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160380, here are decompositions:
- 7 + 160373 = 160380
- 13 + 160367 = 160380
- 23 + 160357 = 160380
- 37 + 160343 = 160380
- 61 + 160319 = 160380
- 67 + 160313 = 160380
- 71 + 160309 = 160380
- 127 + 160253 = 160380
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 160,380 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
