Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515746, here are decompositions:

  • 5 + 515741 = 515746
  • 53 + 515693 = 515746
  • 59 + 515687 = 515746
  • 83 + 515663 = 515746
  • 107 + 515639 = 515746
  • 149 + 515597 = 515746
  • 167 + 515579 = 515746
  • 227 + 515519 = 515746

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 515,746 and was likely granted around 1894.

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