Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105056, here are decompositions:
- 19 + 105037 = 105056
- 37 + 105019 = 105056
- 97 + 104959 = 105056
- 103 + 104953 = 105056
- 109 + 104947 = 105056
- 139 + 104917 = 105056
- 229 + 104827 = 105056
- 277 + 104779 = 105056
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 105 056 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
