Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100090, here are decompositions:

41 + 100049 = 100090
47 + 100043 = 100090
71 + 100019 = 100090
101 + 99989 = 100090
167 + 99923 = 100090
251 + 99839 = 100090
257 + 99833 = 100090
281 + 99809 = 100090

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 100,090 and was likely granted around 1870.

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