Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108580, here are decompositions:

  • 23 + 108557 = 108580
  • 47 + 108533 = 108580
  • 83 + 108497 = 108580
  • 167 + 108413 = 108580
  • 179 + 108401 = 108580
  • 233 + 108347 = 108580
  • 293 + 108287 = 108580
  • 317 + 108263 = 108580

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 108,580 and was likely granted around 1870.

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