Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105344, here are decompositions:
- 3 + 105341 = 105344
- 7 + 105337 = 105344
- 13 + 105331 = 105344
- 67 + 105277 = 105344
- 307 + 105037 = 105344
- 313 + 105031 = 105344
- 373 + 104971 = 105344
- 397 + 104947 = 105344
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 105,344 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
