Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108388, here are decompositions:
- 11 + 108377 = 108388
- 29 + 108359 = 108388
- 41 + 108347 = 108388
- 101 + 108287 = 108388
- 197 + 108191 = 108388
- 227 + 108161 = 108388
- 257 + 108131 = 108388
- 281 + 108107 = 108388
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 108,388 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
