Goldbach decomposition

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.

Possible US patent number

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.
