Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100406, here are decompositions:

3 + 100403 = 100406
13 + 100393 = 100406
43 + 100363 = 100406
73 + 100333 = 100406
109 + 100297 = 100406
127 + 100279 = 100406
139 + 100267 = 100406
193 + 100213 = 100406

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 100,406 and was likely granted around 1870.

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