Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104540, here are decompositions:

3 + 104537 = 104540
13 + 104527 = 104540
61 + 104479 = 104540
67 + 104473 = 104540
157 + 104383 = 104540
193 + 104347 = 104540
229 + 104311 = 104540
307 + 104233 = 104540

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 104,540 and was likely granted around 1870.

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