Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144600, here are decompositions:

7 + 144593 = 144600
11 + 144589 = 144600
17 + 144583 = 144600
23 + 144577 = 144600
31 + 144569 = 144600
37 + 144563 = 144600
59 + 144541 = 144600
61 + 144539 = 144600

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 144,600 and was likely granted around 1873.

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