Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142136, here are decompositions:

  • 13 + 142123 = 142136
  • 37 + 142099 = 142136
  • 79 + 142057 = 142136
  • 97 + 142039 = 142136
  • 199 + 141937 = 142136
  • 229 + 141907 = 142136
  • 283 + 141853 = 142136
  • 307 + 141829 = 142136

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 142,136 and was likely granted around 1872.

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