Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511770, here are decompositions:

  • 13 + 511757 = 511770
  • 47 + 511723 = 511770
  • 59 + 511711 = 511770
  • 67 + 511703 = 511770
  • 79 + 511691 = 511770
  • 101 + 511669 = 511770
  • 137 + 511633 = 511770
  • 139 + 511631 = 511770

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 511,770 and was likely granted around 1893.

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