Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188828, here are decompositions:

  • 37 + 188791 = 188828
  • 61 + 188767 = 188828
  • 109 + 188719 = 188828
  • 127 + 188701 = 188828
  • 151 + 188677 = 188828
  • 337 + 188491 = 188828
  • 397 + 188431 = 188828
  • 421 + 188407 = 188828

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 188,828 and was likely granted around 1875.

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