Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100224, here are decompositions:

  • 11 + 100213 = 100224
  • 17 + 100207 = 100224
  • 31 + 100193 = 100224
  • 41 + 100183 = 100224
  • 71 + 100153 = 100224
  • 73 + 100151 = 100224
  • 167 + 100057 = 100224
  • 181 + 100043 = 100224

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 100,224 and was likely granted around 1870.

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