Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103538, here are decompositions:

67 + 103471 = 103538
139 + 103399 = 103538
151 + 103387 = 103538
181 + 103357 = 103538
307 + 103231 = 103538
367 + 103171 = 103538
397 + 103141 = 103538
439 + 103099 = 103538

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 103 538 and was likely granted around 1870.

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