Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 544400, here are decompositions:

127 + 544273 = 544400
223 + 544177 = 544400
229 + 544171 = 544400
271 + 544129 = 544400
277 + 544123 = 544400
379 + 544021 = 544400
433 + 543967 = 544400
499 + 543901 = 544400

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 544,400 and was likely granted around 1895.

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