Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126860, here are decompositions:

  • 3 + 126857 = 126860
  • 37 + 126823 = 126860
  • 79 + 126781 = 126860
  • 103 + 126757 = 126860
  • 109 + 126751 = 126860
  • 127 + 126733 = 126860
  • 157 + 126703 = 126860
  • 229 + 126631 = 126860

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 126,860 and was likely granted around 1872.

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