Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105402, here are decompositions:
- 5 + 105397 = 105402
- 13 + 105389 = 105402
- 23 + 105379 = 105402
- 29 + 105373 = 105402
- 41 + 105361 = 105402
- 43 + 105359 = 105402
- 61 + 105341 = 105402
- 71 + 105331 = 105402
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 105,402 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
