Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187804, here are decompositions:

11 + 187793 = 187804
17 + 187787 = 187804
41 + 187763 = 187804
53 + 187751 = 187804
83 + 187721 = 187804
167 + 187637 = 187804
173 + 187631 = 187804
257 + 187547 = 187804

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 187,804 and was likely granted around 1875.

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