Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102100, here are decompositions:

23 + 102077 = 102100
29 + 102071 = 102100
41 + 102059 = 102100
101 + 101999 = 102100
113 + 101987 = 102100
137 + 101963 = 102100
179 + 101921 = 102100
227 + 101873 = 102100

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 102,100 and was likely granted around 1870.

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