Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129804, here are decompositions:

  • 11 + 129793 = 129804
  • 41 + 129763 = 129804
  • 47 + 129757 = 129804
  • 67 + 129737 = 129804
  • 71 + 129733 = 129804
  • 97 + 129707 = 129804
  • 163 + 129641 = 129804
  • 173 + 129631 = 129804

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 129,804 and was likely granted around 1872.

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