Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100540, here are decompositions:

3 + 100537 = 100540
17 + 100523 = 100540
23 + 100517 = 100540
29 + 100511 = 100540
47 + 100493 = 100540
71 + 100469 = 100540
137 + 100403 = 100540
149 + 100391 = 100540

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 100,540 and was likely granted around 1870.

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