Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105020, here are decompositions:
- 61 + 104959 = 105020
- 67 + 104953 = 105020
- 73 + 104947 = 105020
- 103 + 104917 = 105020
- 109 + 104911 = 105020
- 151 + 104869 = 105020
- 193 + 104827 = 105020
- 241 + 104779 = 105020
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 105.020 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
