Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511488, here are decompositions:

  • 11 + 511477 = 511488
  • 31 + 511457 = 511488
  • 41 + 511447 = 511488
  • 71 + 511417 = 511488
  • 79 + 511409 = 511488
  • 97 + 511391 = 511488
  • 101 + 511387 = 511488
  • 127 + 511361 = 511488

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 511,488 and was likely granted around 1893.

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