Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156500, here are decompositions:

7 + 156493 = 156500
13 + 156487 = 156500
79 + 156421 = 156500
139 + 156361 = 156500
181 + 156319 = 156500
193 + 156307 = 156500
241 + 156259 = 156500
271 + 156229 = 156500

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 156,500 and was likely granted around 1873.

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