Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108664, here are decompositions:
- 107 + 108557 = 108664
- 131 + 108533 = 108664
- 167 + 108497 = 108664
- 251 + 108413 = 108664
- 263 + 108401 = 108664
- 317 + 108347 = 108664
- 401 + 108263 = 108664
- 431 + 108233 = 108664
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 108,664 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
