Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102012, here are decompositions:

11 + 102001 = 102012
13 + 101999 = 102012
73 + 101939 = 102012
83 + 101929 = 102012
139 + 101873 = 102012
149 + 101863 = 102012
173 + 101839 = 102012
179 + 101833 = 102012

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 102,012 and was likely granted around 1870.

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