Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522866, here are decompositions:

  • 13 + 522853 = 522866
  • 37 + 522829 = 522866
  • 79 + 522787 = 522866
  • 103 + 522763 = 522866
  • 109 + 522757 = 522866
  • 163 + 522703 = 522866
  • 193 + 522673 = 522866
  • 229 + 522637 = 522866

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 522,866 and was likely granted around 1894.

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