Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188004, here are decompositions:

17 + 187987 = 188004
31 + 187973 = 188004
41 + 187963 = 188004
53 + 187951 = 188004
73 + 187931 = 188004
83 + 187921 = 188004
97 + 187907 = 188004
107 + 187897 = 188004

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 188,004 and was likely granted around 1875.

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