Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103888, here are decompositions:

47 + 103841 = 103888
101 + 103787 = 103888
269 + 103619 = 103888
311 + 103577 = 103888
359 + 103529 = 103888
431 + 103457 = 103888
467 + 103421 = 103888
479 + 103409 = 103888

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 103.888 and was likely granted around 1870.

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