Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517940, here are decompositions:

  • 13 + 517927 = 517940
  • 67 + 517873 = 517940
  • 79 + 517861 = 517940
  • 109 + 517831 = 517940
  • 193 + 517747 = 517940
  • 211 + 517729 = 517940
  • 223 + 517717 = 517940
  • 229 + 517711 = 517940

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 517,940 and was likely granted around 1894.

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