Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100200, here are decompositions:

  • 7 + 100193 = 100200
  • 11 + 100189 = 100200
  • 17 + 100183 = 100200
  • 31 + 100169 = 100200
  • 47 + 100153 = 100200
  • 71 + 100129 = 100200
  • 97 + 100103 = 100200
  • 131 + 100069 = 100200

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 100,200 and was likely granted around 1870.

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