Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100012, here are decompositions:

23 + 99989 = 100012
41 + 99971 = 100012
83 + 99929 = 100012
89 + 99923 = 100012
131 + 99881 = 100012
173 + 99839 = 100012
179 + 99833 = 100012
251 + 99761 = 100012

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 100,012 and was likely granted around 1870.

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