Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100080, here are decompositions:

11 + 100069 = 100080
23 + 100057 = 100080
31 + 100049 = 100080
37 + 100043 = 100080
61 + 100019 = 100080
89 + 99991 = 100080
109 + 99971 = 100080
151 + 99929 = 100080

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 100,080 and was likely granted around 1870.

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