Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131234, here are decompositions:

  • 3 + 131231 = 131234
  • 13 + 131221 = 131234
  • 31 + 131203 = 131234
  • 163 + 131071 = 131234
  • 193 + 131041 = 131234
  • 211 + 131023 = 131234
  • 223 + 131011 = 131234
  • 277 + 130957 = 131234

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 131,234 and was likely granted around 1872.

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