Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100844, here are decompositions:

43 + 100801 = 100844
97 + 100747 = 100844
103 + 100741 = 100844
151 + 100693 = 100844
223 + 100621 = 100844
307 + 100537 = 100844
397 + 100447 = 100844
433 + 100411 = 100844

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 100,844 and was likely granted around 1870.

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