Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516810, here are decompositions:

  • 17 + 516793 = 516810
  • 53 + 516757 = 516810
  • 83 + 516727 = 516810
  • 89 + 516721 = 516810
  • 97 + 516713 = 516810
  • 101 + 516709 = 516810
  • 109 + 516701 = 516810
  • 131 + 516679 = 516810

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 516,810 and was likely granted around 1894.

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