Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103878, here are decompositions:

11 + 103867 = 103878
37 + 103841 = 103878
41 + 103837 = 103878
67 + 103811 = 103878
109 + 103769 = 103878
179 + 103699 = 103878
191 + 103687 = 103878
197 + 103681 = 103878

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 103.878 and was likely granted around 1870.

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