Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154510, here are decompositions:

17 + 154493 = 154510
23 + 154487 = 154510
71 + 154439 = 154510
101 + 154409 = 154510
137 + 154373 = 154510
197 + 154313 = 154510
233 + 154277 = 154510
263 + 154247 = 154510

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 154,510 and was likely granted around 1873.

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