Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144500, here are decompositions:

3 + 144497 = 144500
19 + 144481 = 144500
61 + 144439 = 144500
73 + 144427 = 144500
151 + 144349 = 144500
193 + 144307 = 144500
211 + 144289 = 144500
229 + 144271 = 144500

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 144,500 and was likely granted around 1873.

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