Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105018, here are decompositions:

19 + 104999 = 105018
31 + 104987 = 105018
47 + 104971 = 105018
59 + 104959 = 105018
71 + 104947 = 105018
101 + 104917 = 105018
107 + 104911 = 105018
127 + 104891 = 105018

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 105.018 and was likely granted around 1870.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
