Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512688, here are decompositions:

  • 5 + 512683 = 512688
  • 17 + 512671 = 512688
  • 31 + 512657 = 512688
  • 47 + 512641 = 512688
  • 67 + 512621 = 512688
  • 79 + 512609 = 512688
  • 97 + 512591 = 512688
  • 107 + 512581 = 512688

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 512,688 and was likely granted around 1893.

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