Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470728, here are decompositions:

  • 17 + 470711 = 470728
  • 59 + 470669 = 470728
  • 101 + 470627 = 470728
  • 107 + 470621 = 470728
  • 131 + 470597 = 470728
  • 149 + 470579 = 470728
  • 197 + 470531 = 470728
  • 227 + 470501 = 470728

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 470,728 and was likely granted around 1891.

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