Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133900, here are decompositions:

23 + 133877 = 133900
47 + 133853 = 133900
89 + 133811 = 133900
131 + 133769 = 133900
167 + 133733 = 133900
191 + 133709 = 133900
227 + 133673 = 133900
251 + 133649 = 133900

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 133,900 and was likely granted around 1872.

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