Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515764, here are decompositions:

  • 3 + 515761 = 515764
  • 23 + 515741 = 515764
  • 71 + 515693 = 515764
  • 83 + 515681 = 515764
  • 101 + 515663 = 515764
  • 113 + 515651 = 515764
  • 167 + 515597 = 515764
  • 257 + 515507 = 515764

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 515,764 and was likely granted around 1894.

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