Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105208, here are decompositions:

41 + 105167 = 105208
71 + 105137 = 105208
101 + 105107 = 105208
137 + 105071 = 105208
317 + 104891 = 105208
359 + 104849 = 105208
419 + 104789 = 105208
449 + 104759 = 105208

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 105.208 and was likely granted around 1870.

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