Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511658, here are decompositions:

  • 31 + 511627 = 511658
  • 67 + 511591 = 511658
  • 79 + 511579 = 511658
  • 109 + 511549 = 511658
  • 139 + 511519 = 511658
  • 151 + 511507 = 511658
  • 181 + 511477 = 511658
  • 211 + 511447 = 511658

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 511,658 and was likely granted around 1893.

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