Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103900, here are decompositions:

11 + 103889 = 103900
59 + 103841 = 103900
89 + 103811 = 103900
113 + 103787 = 103900
131 + 103769 = 103900
197 + 103703 = 103900
257 + 103643 = 103900
281 + 103619 = 103900

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 103,900 and was likely granted around 1870.

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