Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105904, here are decompositions:

5 + 105899 = 105904
41 + 105863 = 105904
137 + 105767 = 105904
251 + 105653 = 105904
347 + 105557 = 105904
401 + 105503 = 105904
467 + 105437 = 105904
503 + 105401 = 105904

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 105.904 and was likely granted around 1870.

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