Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511512, here are decompositions:

  • 5 + 511507 = 511512
  • 59 + 511453 = 511512
  • 73 + 511439 = 511512
  • 103 + 511409 = 511512
  • 151 + 511361 = 511512
  • 179 + 511333 = 511512
  • 223 + 511289 = 511512
  • 233 + 511279 = 511512

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 511,512 and was likely granted around 1893.

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