Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100856, here are decompositions:

3 + 100853 = 100856
109 + 100747 = 100856
157 + 100699 = 100856
163 + 100693 = 100856
307 + 100549 = 100856
337 + 100519 = 100856
373 + 100483 = 100856
397 + 100459 = 100856

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 100,856 and was likely granted around 1870.

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