Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481664, here are decompositions:

  • 13 + 481651 = 481664
  • 31 + 481633 = 481664
  • 151 + 481513 = 481664
  • 163 + 481501 = 481664
  • 277 + 481387 = 481664
  • 367 + 481297 = 481664
  • 433 + 481231 = 481664
  • 457 + 481207 = 481664

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 481,664 and was likely granted around 1892.

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