Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186600, here are decompositions:

13 + 186587 = 186600
17 + 186583 = 186600
19 + 186581 = 186600
31 + 186569 = 186600
131 + 186469 = 186600
149 + 186451 = 186600
163 + 186437 = 186600
181 + 186419 = 186600

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 186,600 and was likely granted around 1875.

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