Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127726, here are decompositions:

  • 17 + 127709 = 127726
  • 23 + 127703 = 127726
  • 47 + 127679 = 127726
  • 83 + 127643 = 127726
  • 89 + 127637 = 127726
  • 197 + 127529 = 127726
  • 233 + 127493 = 127726
  • 239 + 127487 = 127726

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 127,726 and was likely granted around 1872.

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