Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102128, here are decompositions:

7 + 102121 = 102128
67 + 102061 = 102128
97 + 102031 = 102128
109 + 102019 = 102128
127 + 102001 = 102128
151 + 101977 = 102128
199 + 101929 = 102128
211 + 101917 = 102128

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 102,128 and was likely granted around 1870.

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