Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104900, here are decompositions:

31 + 104869 = 104900
73 + 104827 = 104900
97 + 104803 = 104900
127 + 104773 = 104900
139 + 104761 = 104900
157 + 104743 = 104900
193 + 104707 = 104900
199 + 104701 = 104900

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 104,900 and was likely granted around 1870.

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