Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105644, here are decompositions:
- 31 + 105613 = 105644
- 37 + 105607 = 105644
- 43 + 105601 = 105644
- 103 + 105541 = 105644
- 127 + 105517 = 105644
- 271 + 105373 = 105644
- 277 + 105367 = 105644
- 283 + 105361 = 105644
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 105.644 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
