Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127170, here are decompositions:

  • 7 + 127163 = 127170
  • 13 + 127157 = 127170
  • 31 + 127139 = 127170
  • 37 + 127133 = 127170
  • 47 + 127123 = 127170
  • 67 + 127103 = 127170
  • 89 + 127081 = 127170
  • 137 + 127033 = 127170

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 127,170 and was likely granted around 1872.

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