Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184138, here are decompositions:
- 5 + 184133 = 184138
- 107 + 184031 = 184138
- 131 + 184007 = 184138
- 167 + 183971 = 184138
- 179 + 183959 = 184138
- 257 + 183881 = 184138
- 431 + 183707 = 184138
- 557 + 183581 = 184138
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 184,138 and was likely granted around 1875.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
