Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154450, here are decompositions:

11 + 154439 = 154450
41 + 154409 = 154450
137 + 154313 = 154450
173 + 154277 = 154450
239 + 154211 = 154450
269 + 154181 = 154450
293 + 154157 = 154450
353 + 154097 = 154450

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 154,450 and was likely granted around 1873.

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