Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100404, here are decompositions:

  • 11 + 100393 = 100404
  • 13 + 100391 = 100404
  • 41 + 100363 = 100404
  • 43 + 100361 = 100404
  • 47 + 100357 = 100404
  • 61 + 100343 = 100404
  • 71 + 100333 = 100404
  • 107 + 100297 = 100404

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 100,404 and was likely granted around 1870.

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