Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104872, here are decompositions:

  • 3 + 104869 = 104872
  • 23 + 104849 = 104872
  • 41 + 104831 = 104872
  • 71 + 104801 = 104872
  • 83 + 104789 = 104872
  • 113 + 104759 = 104872
  • 149 + 104723 = 104872
  • 179 + 104693 = 104872

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 104,872 and was likely granted around 1870.

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