Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105490, here are decompositions:

23 + 105467 = 105490
41 + 105449 = 105490
53 + 105437 = 105490
83 + 105407 = 105490
89 + 105401 = 105490
101 + 105389 = 105490
131 + 105359 = 105490
149 + 105341 = 105490

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 105.490 and was likely granted around 1870.

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