Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104400, here are decompositions:

  • 7 + 104393 = 104400
  • 17 + 104383 = 104400
  • 19 + 104381 = 104400
  • 31 + 104369 = 104400
  • 53 + 104347 = 104400
  • 73 + 104327 = 104400
  • 89 + 104311 = 104400
  • 103 + 104297 = 104400

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 104,400 and was likely granted around 1870.

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