Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108644, here are decompositions:
- 7 + 108637 = 108644
- 13 + 108631 = 108644
- 73 + 108571 = 108644
- 103 + 108541 = 108644
- 127 + 108517 = 108644
- 181 + 108463 = 108644
- 223 + 108421 = 108644
- 373 + 108271 = 108644
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 108,644 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
