Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190436, here are decompositions:

67 + 190369 = 190436
79 + 190357 = 190436
97 + 190339 = 190436
139 + 190297 = 190436
193 + 190243 = 190436
229 + 190207 = 190436
277 + 190159 = 190436
307 + 190129 = 190436

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 190,436 and was likely granted around 1875.

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