Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 557806, here are decompositions:

  • 3 + 557803 = 557806
  • 5 + 557801 = 557806
  • 17 + 557789 = 557806
  • 47 + 557759 = 557806
  • 59 + 557747 = 557806
  • 89 + 557717 = 557806
  • 113 + 557693 = 557806
  • 167 + 557639 = 557806

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 557,806 and was likely granted around 1895.

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