Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164120, here are decompositions:

  • 3 + 164117 = 164120
  • 7 + 164113 = 164120
  • 31 + 164089 = 164120
  • 97 + 164023 = 164120
  • 109 + 164011 = 164120
  • 127 + 163993 = 164120
  • 139 + 163981 = 164120
  • 193 + 163927 = 164120

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 164,120 and was likely granted around 1874.

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