Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104580, here are decompositions:

  • 19 + 104561 = 104580
  • 29 + 104551 = 104580
  • 31 + 104549 = 104580
  • 37 + 104543 = 104580
  • 43 + 104537 = 104580
  • 53 + 104527 = 104580
  • 67 + 104513 = 104580
  • 89 + 104491 = 104580

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 104,580 and was likely granted around 1870.

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