Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120810, here are decompositions:

  • 31 + 120779 = 120810
  • 43 + 120767 = 120810
  • 47 + 120763 = 120810
  • 61 + 120749 = 120810
  • 71 + 120739 = 120810
  • 73 + 120737 = 120810
  • 89 + 120721 = 120810
  • 97 + 120713 = 120810

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 120,810 and was likely granted around 1871.

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