Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520320, here are decompositions:

  • 7 + 520313 = 520320
  • 11 + 520309 = 520320
  • 13 + 520307 = 520320
  • 23 + 520297 = 520320
  • 29 + 520291 = 520320
  • 41 + 520279 = 520320
  • 79 + 520241 = 520320
  • 107 + 520213 = 520320

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 520,320 and was likely granted around 1894.

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