Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 580640, here are decompositions:

  • 7 + 580633 = 580640
  • 13 + 580627 = 580640
  • 79 + 580561 = 580640
  • 127 + 580513 = 580640
  • 163 + 580477 = 580640
  • 223 + 580417 = 580640
  • 283 + 580357 = 580640
  • 337 + 580303 = 580640

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 580,640 and was likely granted around 1896.

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