Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500818, here are decompositions:

  • 11 + 500807 = 500818
  • 41 + 500777 = 500818
  • 89 + 500729 = 500818
  • 239 + 500579 = 500818
  • 251 + 500567 = 500818
  • 317 + 500501 = 500818
  • 347 + 500471 = 500818
  • 359 + 500459 = 500818

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 500,818 and was likely granted around 1893.

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