Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105306, here are decompositions:
- 29 + 105277 = 105306
- 37 + 105269 = 105306
- 43 + 105263 = 105306
- 53 + 105253 = 105306
- 67 + 105239 = 105306
- 79 + 105227 = 105306
- 107 + 105199 = 105306
- 139 + 105167 = 105306
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 105,306 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
