Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103640, here are decompositions:

67 + 103573 = 103640
73 + 103567 = 103640
79 + 103561 = 103640
157 + 103483 = 103640
241 + 103399 = 103640
283 + 103357 = 103640
307 + 103333 = 103640
349 + 103291 = 103640

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 103.640 and was likely granted around 1870.

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