Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103100, here are decompositions:

7 + 103093 = 103100
13 + 103087 = 103100
31 + 103069 = 103100
223 + 102877 = 103100
229 + 102871 = 103100
241 + 102859 = 103100
271 + 102829 = 103100
307 + 102793 = 103100

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 103,100 and was likely granted around 1870.

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