Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540450, here are decompositions:

13 + 540437 = 540450
17 + 540433 = 540450
59 + 540391 = 540450
61 + 540389 = 540450
67 + 540383 = 540450
73 + 540377 = 540450
83 + 540367 = 540450
101 + 540349 = 540450

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 540,450 and was likely granted around 1894.

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