Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100170, here are decompositions:

  • 17 + 100153 = 100170
  • 19 + 100151 = 100170
  • 41 + 100129 = 100170
  • 61 + 100109 = 100170
  • 67 + 100103 = 100170
  • 101 + 100069 = 100170
  • 113 + 100057 = 100170
  • 127 + 100043 = 100170

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 100,170 and was likely granted around 1870.

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