Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108128, here are decompositions:
- 19 + 108109 = 108128
- 67 + 108061 = 108128
- 157 + 107971 = 108128
- 271 + 107857 = 108128
- 337 + 107791 = 108128
- 367 + 107761 = 108128
- 409 + 107719 = 108128
- 457 + 107671 = 108128
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 108,128 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
