Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103806, here are decompositions:

5 + 103801 = 103806
19 + 103787 = 103806
37 + 103769 = 103806
83 + 103723 = 103806
103 + 103703 = 103806
107 + 103699 = 103806
137 + 103669 = 103806
149 + 103657 = 103806

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 103.806 and was likely granted around 1870.

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