Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105206, here are decompositions:

7 + 105199 = 105206
109 + 105097 = 105206
337 + 104869 = 105206
379 + 104827 = 105206
433 + 104773 = 105206
463 + 104743 = 105206
499 + 104707 = 105206
523 + 104683 = 105206

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 105 206 and was likely granted around 1870.

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