Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100686, here are decompositions:

13 + 100673 = 100686
17 + 100669 = 100686
37 + 100649 = 100686
73 + 100613 = 100686
127 + 100559 = 100686
137 + 100549 = 100686
139 + 100547 = 100686
149 + 100537 = 100686

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 100,686 and was likely granted around 1870.

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