Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187004, here are decompositions:

127 + 186877 = 187004
163 + 186841 = 187004
211 + 186793 = 187004
241 + 186763 = 187004
271 + 186733 = 187004
277 + 186727 = 187004
421 + 186583 = 187004
523 + 186481 = 187004

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 187,004 and was likely granted around 1875.

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