Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164100, here are decompositions:

  • 7 + 164093 = 164100
  • 11 + 164089 = 164100
  • 29 + 164071 = 164100
  • 43 + 164057 = 164100
  • 61 + 164039 = 164100
  • 89 + 164011 = 164100
  • 103 + 163997 = 164100
  • 107 + 163993 = 164100

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 164,100 and was likely granted around 1874.

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