Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500280, here are decompositions:

23 + 500257 = 500280
31 + 500249 = 500280
41 + 500239 = 500280
43 + 500237 = 500280
47 + 500233 = 500280
71 + 500209 = 500280
83 + 500197 = 500280
101 + 500179 = 500280

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 500,280 and was likely granted around 1893.

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