Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104520, here are decompositions:

  • 7 + 104513 = 104520
  • 29 + 104491 = 104520
  • 41 + 104479 = 104520
  • 47 + 104473 = 104520
  • 61 + 104459 = 104520
  • 103 + 104417 = 104520
  • 127 + 104393 = 104520
  • 137 + 104383 = 104520

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 104,520 and was likely granted around 1870.

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