Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187050, here are decompositions:

7 + 187043 = 187050
23 + 187027 = 187050
41 + 187009 = 187050
47 + 187003 = 187050
103 + 186947 = 187050
167 + 186883 = 187050
173 + 186877 = 187050
179 + 186871 = 187050

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 187,050 and was likely granted around 1875.

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