Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105356, here are decompositions:
- 19 + 105337 = 105356
- 37 + 105319 = 105356
- 79 + 105277 = 105356
- 103 + 105253 = 105356
- 127 + 105229 = 105356
- 157 + 105199 = 105356
- 337 + 105019 = 105356
- 397 + 104959 = 105356
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 105,356 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
