Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131298, here are decompositions:

  • 5 + 131293 = 131298
  • 31 + 131267 = 131298
  • 47 + 131251 = 131298
  • 67 + 131231 = 131298
  • 127 + 131171 = 131298
  • 149 + 131149 = 131298
  • 197 + 131101 = 131298
  • 227 + 131071 = 131298

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 131,298 and was likely granted around 1872.

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