Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105804, here are decompositions:

37 + 105767 = 105804
43 + 105761 = 105804
53 + 105751 = 105804
71 + 105733 = 105804
103 + 105701 = 105804
113 + 105691 = 105804
131 + 105673 = 105804
137 + 105667 = 105804

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 105.804 and was likely granted around 1870.

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