Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518040, here are decompositions:

23 + 518017 = 518040
41 + 517999 = 518040
59 + 517981 = 518040
73 + 517967 = 518040
109 + 517931 = 518040
113 + 517927 = 518040
139 + 517901 = 518040
163 + 517877 = 518040

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 518,040 and was likely granted around 1894.

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