Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512730, here are decompositions:

  • 13 + 512717 = 512730
  • 17 + 512713 = 512730
  • 19 + 512711 = 512730
  • 47 + 512683 = 512730
  • 59 + 512671 = 512730
  • 67 + 512663 = 512730
  • 73 + 512657 = 512730
  • 89 + 512641 = 512730

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 512,730 and was likely granted around 1893.

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