Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133898, here are decompositions:

  • 67 + 133831 = 133898
  • 97 + 133801 = 133898
  • 181 + 133717 = 133898
  • 229 + 133669 = 133898
  • 241 + 133657 = 133898
  • 379 + 133519 = 133898
  • 547 + 133351 = 133898
  • 571 + 133327 = 133898

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 133,898 and was likely granted around 1872.

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