Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105106, here are decompositions:

83 + 105023 = 105106
107 + 104999 = 105106
173 + 104933 = 105106
227 + 104879 = 105106
257 + 104849 = 105106
317 + 104789 = 105106
347 + 104759 = 105106
383 + 104723 = 105106

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 105,106 and was likely granted around 1870.

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